The microwave bomb.

It's time to face Lyons.

I stop and turn around so quickly that it catches Lyons off guard. He flinches and slides to a standstill, fifteen feet between us. We're framed by a unicorn-themed carousel and a pirate ship. Not the most epic of battlegrounds, but I enjoy the juxtaposition.

I hold my wrist up, revealing the beeping watch that I synced with the bomb's timer when I was with Cobb. I reach up and push a b.u.t.ton to stop it. "Do you know what that means?"

Dread Lyons's seven black eyes squint. He's still in there somewhere. "It means you've lost." I take the backpack off, unzip it, and dump a tire-repair kit onto the ground. I don't need to tell him that Cobb took the bomb, that he was going to find someplace to contain it or dump it in the ocean, which would reduce the weapon's impact. Either way, the colony would survive. The war he longed for and the vengeance he craved-for the deaths he caused-would never come to pa.s.s.

Not against the Dread, anyway. The cold gaze in his seven eyes says he'll be satisfied, to some extent, by reducing my body to pulp. The only question remaining is which one of us will take action first? The answer is never really in question. I make my move before the thought finishes.

The handgun hidden among the tire iron, jack, flares, and orange cones is a 9 mm recovered from the SUV. It lacks the punch I'd need to kill Lyons, which is unfortunate, but it's a good start. The weapon comes up in an unflinching two-hand grip.

I pull the trigger. Just once. The black orb on the side of Lyons's head erupts, spewing a mixture of oily white and glowing red fluids.

His head snaps back, his jaw drops open, and tendrils whip the air. A roar warbles over the quiet Storyland walkways. When he's done, he turns the remaining six eyes toward me. I can feel his loathing for me. Like the Dread whispering, it's in my head, wordless, but clear.

And without effect.

My second shot bursts the Dread eye on the left side of his head. He shrieks again, and this time charges blindly, head turned away to protect his remaining eyes. This is it. I can end him right here.

I slip into the mirror world intending to reenter the real world, inside Lyons, just long enough to create a me-sized hole in his chest. Storyland disappears, replaced by a dark, green-veined swamp. With an eye still tuned to the real world, I watch Lyons charge. I visualize my attack, picturing the few simple steps. Eyes closed and breath held, I'll arrive inside his body. Just for a second. Then I'll slip back into the mirror world. Carried by his forward motion, I'll be flung into the swamp, the landing buffered by a foot of water. Simple.

But that's not exactly how it works out. Not even close.

Lyons turns his ugly head forward at that last second, slips fully into the mirror world, and swipes out with one of his big clawed hands. I manage to squeeze off three more rounds before I'm struck, but they just get lodged in the thick armor that is now his forehead.

The one bit of luck is that the curved tip of his long, mole claw misses me. While I'm not impaled or severed in two, the result is close to being lifted off the ground and flung by a rock-solid, oversize lacrosse stick. The impact catches me below the arm. I feel my ribs flex and then break. Three of them. Snap, snap, snap. And then I'm doing a repeat performance of Pinocchio's acrobatics, soaring through the air. As I reach the apex of my arc, I've got to make a few choices. Lyons is already chasing after me, so there won't be time to think once I land. He might just kill me, but I suspect he's going to toy with me. I'm a mouse to him now, and, like a cat, he's going to play with me until my body simply gives up.

Luckily for me, I'm a mouse with world-cla.s.s military training, a killer instinct, and fearless nature. Mind made up, I finish my fall in the Dread world, letting the water soften my landing. I take the hit on my left side, protecting my freshly broken ribs, and waste no time getting to my feet. I've still got one more challenge to overcome before avoiding this immediate danger. Injured and soaked through, I need to jump at least three feet up.

I bend my knees and shove hard, three seconds until Lyons's arrival. The wet earth squishes beneath my feet, absorbing some of my energy. The water clings to my legs, not wanting to let me go. But then I'm free and rising. Two seconds to go. I lift my legs like a frog and, with no time left, return to the real world. Lyons follows and reaches for me but grabs a large plastic horse instead.

I land on the carousel floor between a unicorn and Cinderella's pumpkin chariot. Lyons is in a slightly more precarious situation. While his right arm is free to move, the rest of him is embedded within metal bars, a double set of Pegasus, and the floor of the ride. He wrenches the interfering horse out of the floor and tosses it aside. His free arm swings out, gouging a trough through the floor where I'd been a moment before. Even with my quick backward roll, he nearly catches me.

But now I'm on my feet and he's trapped.

"This could have gone differently," I tell him, reaching over my shoulder. "You were naive when you destroyed the first colony. I can look past that. And we lost nearly everything, you and I." Lyons stops struggling against the carousel. Actually appears to be listening. "But it could have stopped there. It should have stopped there. Both sides drew blood, but if we're honest, you and I, and the rest of humanity, have done far more damage. I didn't know fear until a few days ago, but in that short amount of time, I learned that it can be conquered, like any other emotion."

I draw Faithful, feeling stronger with the blade in my hand.

Lyons eyes the weapon but doesn't move. Could he actually be considering what I'm saying? Was there ever a time when he listened-really listened-to me? I'm not sure. But I'm going to give him a chance. For Maya, whose fate is still a mystery, and who is the reason I need to end this.

"I'm going to ask you this only once," I say, stepping closer but still out of reach. "Can you let it go? Can you move past your childhood and loss, forgive your enemy, and move on? Show the Dread that we are better than them. Show them that humanity is more than war and destruction. Show them how to forgive."

I grip the machete tightly, antic.i.p.ating his reply.

Unfortunately, I don't antic.i.p.ate exactly how the response will be delivered.

Lyons disappears. It's a blink. A fraction of a second. And when he returns, he's a step closer, driving a hook-clawed hand into my gut like a giant fist. I pitch forward and fall back, gasping for air, but am thankful it wasn't the claws' sharp tip that had made contact.

The carousel spins as Lyons tries to reach me again. But he's locked up once more. Problem is, he already knows how to overcome that problem. When he disappears again, I throw myself away from him, injured but mobile and still wielding Faithful.

When Lyons returns, he's no longer trapped. He's still inside the carousel, but he's standing on the floor, not in it. With a savage roar, he follows my path through the ride, destroying unicorns, horses, and fairy-tale creatures with brutal efficiency.

The ride, it seems, is over. One lap around the slowly spinning carousel is all I'm going to get. After that, I'll be slowed by the ruins and he can continue plowing his way through.

I've got no tricks left that he can't match.

So we'll do it the old-fashioned way. Part man to used-to-be man. I step off the carousel, walking calmly, my back to Lyons. When I hear him smash free of the now-ruined ride, I turn around to face him, left hand clutching my side, right hand holding Faithful.

"C'mon then," I say. "Let's get this over with."

He stalks toward me, pausing to shake his head, throwing streams of glowing red from his ruined eyes. I take a quick look around for the pistol. It's gone.

Standing almost casually, I wait for the charge.

When it comes, I'm almost surprised by its quickness.

Almost.

Lyons's primary attack has been swiping at me with those big claws. He repeats the same tactic, or perhaps instinct, once again. I duck beneath the strike, step to the side, and hack down as the lumbering monster that was my father-in-law rumbles past. The chiseled blade tip cuts a gouge in Lyons's flank. It's hardly a mortal blow, but I've severed several of the thick, external veins covering his body. Blood loss will eventually slow him. Emphasis on eventually.

Reacting to the pain of the cut, Lyons brings his rear limb up and kicks out like a horse. Quick reflexes and Lyons's broad foot dispersing the force of the blow over a wider area save me. But the kick is still solid enough to send me sprawling toward my broken ribs. Fear or no fear, the impact will nearly blind me with pain.

I slip into the mirror world. The swamp buffers my landing, sparing my ribs. I'm about to slip back when I realize I'm no longer alone. And it's not Lyons. Holy s.h.i.t, I think as I turn my head in a slow arc. The swampy clearing is surrounded by towering trees, sagging low with twisting black coils. But standing among the trees are hundreds of Dread. Bulls, pugs, mothmen, mammoths, Medusa-hands, and crocs. There are even two of those ma.s.sive winged centipedes and a cloud of small bats circling the area.

They've come to watch the end of the two men who nearly destroyed their world. We're probably infamous characters to the Dread. Destroyers of colonies. Invaders. I suppose watching the two of us fight-the fearless man versus the Dread man-would be a little bit like watching Osama bin Laden and Hitler go at it.

Not quite, I remind myself. I did help save this colony and prevent a war between worlds. So maybe they're just here to cheer me on? Given the way they're all lingering at the clearing's fringe, they're clearly not here to help, though I suspect they might also be here to deal with the winner.

Lyons unknowingly takes advantage of the distraction. He explodes into the mirror world, slams a hooked claw into my shoulder and another into my side. I shout in pain as I'm lifted out of the swamp and slammed back down. Water surges into my mouth as the air is knocked from my lungs. I can't even scream when the hooked claws are yanked free.

I clear my head from the water, coughing and gasping, but am pinned. Lyons is above me, leaning closer. At first I think he's going to simply bite my face off with those snapping jaws, but then I note the tendrils writhing on his face. With those, he can enter my mind.

He can make me afraid.

He can erase my memory again.

It's a fate worse than death.

I'm about to use my last seconds to cuss him out when a voice shouts out, bold and strong. "Father!"

Lyons pauses. Glances up.

I follow his gaze, seeing Maya upside down. She's a mess and physically afraid, but I haven't seen this stern look in her eyes since before Simon died. She wades through the muck and water. Raises a finger at the monster she knows is her father. "You let my husband go."

For a moment, Lyons appears to consider her demand, but then his eyes squint. He roars at Maya in a way that says, you're next. It's all the motivation I need.

I slip into the real world, somersault forward, and stand.

It takes just a second, but I'm now in a race. If Lyons chases me and enters this world while I'm still here, he'll erase me. But if I move first ... I shift back into the mirror world and miss my mark. I had intended to emerge inside Lyons, to replace his insides with myself. But he's stepped forward, and I've come up behind him, weaponless.

Technically, I've been trained to be a weapon, but that was against people, not ... whatever Lyons has become. My best chance of stopping him was punching a hole in his body by slipping through dimensions. But now ...

My eyes widen. I still have one weapon-the a.s.sa.s.sin's best friend, hidden in a pocket all this time, waiting for its deadly potential to be released.

Lyons swipes at me with his tail, but I'm already leaping for his back. The appendage sweeps beneath my feet. I land on his hard back, grunting as my ribs are bent inward. I manage to cling to the protective plates covering him and use my newfound strength to hoist myself higher. Lyons reaches for me, twisting his arms back, but his bulky muscles lack the flexibility. He spins and roars, reaching, clawing. I climb over his back, sliding up over the line of mammoth tendrils covering his spine, and stop at his plated shoulder blades.

In range of my target, I prepare myself for what will be one of the most basic, while at the same time complex, attacks I have ever performed. Step 1 is old-school, and I handle it with practiced fluidity. Holding on to Lyons's back with one hand, I reach into my pocket with the other, gripping the oscillium handle of the coiled garrote. I pull the line from my pocket, leap higher, and swing the line downward. As my jump reaches its pinnacle, the second handle swings down and around Lyons's neck. I pluck it from the air with my free hand-and drop. Pulling the line tight with all of my weight and strength around Lyons's neck.

Now comes the hard part.

While oscillium can reside in one frequency of reality, or all frequencies simultaneously, biological creatures-human and Dread-reside in one dimension at a time. And right now, the garrote resides in whichever frequency I am in, coming along for the ride. While I've been able to look into both dimensions at once, I simply changed the perception of one eye. What I need to do now is different, because in a second Lyons is going to slip back into the real world, and I need to keep my weight on the line. So I shift part of me and then all of me, not between frequencies, but into all frequencies: A, B, and B flat. The garrote matches my multifrequency state.

White-hot agony tears through my body and mind, but I never relinquish my grip. Lyons's roar becomes a choked gurgle, and he shifts back to the real world.

But I'm already there, pulling on him.

He goes back to the Dread world, where I still exist, having never left. I physically and mentally experience all frequencies of human and Dread realities. The sensation is nearly overwhelming, but there is also a kind of energy in the place, painful but powerful, and it sees me through until Lyons's body quivers and buckles.

He falls to his knees, landing in the Dread swamp. Still, I cling and pull. The oscillium wire slips through Lyons's flesh, cutting through veins, sinews, vocal cords, and larynx. The life goes out of him and the monster tumbles back, falling toward the water with me on his back.

I leave the mirror world behind and am flung back onto the concrete walkway, eyes still trained on all frequencies. I watch as Lyons topples over, falling through me to land, with a splash, in the Dread swamp. Glowing red blood seeps from his ruined neck, pluming out into the dark water. I get to my feet, watching both worlds as Maya falls to her knees, hand to her mouth, weeping for the monster that raised her.

I walk over the solid Storyland pavement, finding Faithful, which I stop to pick up and sheath on my back. Then I step up to Maya, the woman I forgot, betrayed, remembered, and never really stopped loving, and fall to my knees. When I slip back into the mirror world, she flinches back in surprise, but I don't see fear in her eyes. Is that what they did to her? Did they make her like me?

"You're not afraid?" I ask.

"Of you? Never." She falls forward, wrapping her arms around me. We stay there, immersed in the swamp of a mirror dimension, holding each other for several minutes.

"It wasn't your fault," I say, jumping straight to the crux of that matter that took her from me.

"I know," she says, squeezing me harder, which still isn't very hard. Suddenly aware of her fragile state, not to mention the fact that I'm probably bleeding out, I take one last look around.

The Dread watch us with quiet fascination.

"Are we done?" I ask, the question as much about me and Maya as the rest of the world on the brink of annihilation.

When I get no response or even a quizzical look, I shout the words, sending a burst of fear in all directions-except Maya's. "Are we done!"

The reply comes as a whisper in my mind. "It is finished."

I sag in Maya's arms. "Love you."

By the time she replies, we're kneeling on the concrete walkway of Storyland, breathing ammonia-free air in a world freed from dread.

EPILOGUE.

Cobb found us ten minutes later. He'd managed to get the mircrowave bomb to a bank. Once he revealed he was carrying a bomb that would cook everyone and everything within a mile unless it was contained inside something metal and grounded, the manager let him put it inside the vault. Under normal circ.u.mstances, I doubt the manager would have believed the story, but the whole world was hopped up on fear. Cobb saved the city and helped save the world without ever setting foot in the mirror world, which is fine by him. We've remained friends, but he wanted no part in what I'm up to today.

Maya, on the other hand, stands by my side, hidden in the woods of New Hampshire. She's been eating well over the past month. Recovering, body and soul. My body is recovering, too. I required a blood transfusion, which nearly didn't come in time, thanks to all the violence ravaging supplies. But there was an outpouring of goodwill following the cease-fire of Dread fear, and I pulled through. And now I'm not even sore. Whatever part of me is Dread still heals fast. At least physically. Despite the return of my memory and fearless nature, there are things I would like to forget. Things I've done and that I've endured.

Mostly things I've done. I can justify them, sure. I was one of the good guys, preventing terrorism or international organized crime. But the truth is that I don't know. Being fearless means not being afraid to carry out orders. There's no way to know if someone took advantage of that. I take solace in the knowledge that I saved the world.

Two worlds.

Things have been good between Maya and me. Rough, but good. A lot of the rough has to do with my unfettered honesty. I say what I think. But it also leaves no doubt about my honesty, and when I tell her I love her, she believes me. We've talked a lot. About Simon's death. About her father's quest for vengeance. About Winters. To my surprise, she understood and forgave me. Life will never be in short supply of painful memories, but we're moving forward. Together. And that's a gift. I thought I'd lost her forever.

And we're not the only ones healing. The heavy blanket of fear driving people to the streets and nations to the brink of war has lifted worldwide. I've gone over the timing and, as best as I can figure it, the Dread removed its influence from humanity, worldwide, when the matriarch spoke the words, "It is finished."

While I'm sure people are still getting the chills when they pa.s.s a Dread, I don't think the mirror world will be poking the human race anytime soon. We might not have the natural ability to move between worlds yet, but humanity is no longer a slave to the slow machinations of evolution. Technology allows us to do things we're not quite ready for and don't fully understand. Maybe we'll be ready to play nice with the Dread someday-they'll need a different name-but until then, I'm going to do what I can to slow the process.

"They're everywhere," Maya says, lowering the binoculars.

We're looking at the outside of the Neuro building. The branch of the CIA that supported Lyons's quiet war has descended on the facility. Where there was once a collection of black and gray vehicles in the parking lot, they're all just black now. I look for a splash of orange, remembering Winters's sacrifice, and a little bit more.

I take the binoculars from Maya and scan the area. There's plenty of security. Far more than before. But the building is still being repaired. There are c.h.i.n.ks in the armor. All I really need to do is get beyond the d.a.m.n electrified fence, which still exists in both worlds.

I stand from my crouched position, ready to make my move.

"Are you sure you need to do this?" Maya asks.

"Everything is in there," I say. "I don't think the Dread will be so merciful a second time around."

"Let the boy go," Allenby says from my other side. Her poofy hair is tied back. The look in her eyes says she'd like to do this herself. She's been by our side since we returned to the airport, bloodied but alive. We've been staying in the home she'd lived in with Hugh, the home she couldn't bring herself to sell, just fifteen minutes from Neuro. "He might not be able to stop the demons haunting our souls, but he can at least remove them from this world."

Allenby, like me, was more deeply involved in Neuro. She feels the weight of what happened and is determined to prevent it from happening again. Today was her idea. I only hope I can do what she's asked.

Maya sighs, gives me a sheepish smile, and kisses my cheek. "Be careful."

"Have no fear," I say and slip into the mirror world. Hand on Faithful, which is sheathed on my back, I scour the surrounding area. Not a living Dread in sight. There are plenty of dead, though, corpses from my encounter with the local matriarch. Her flesh has fallen away, leaving a large skeleton rising up the side of the oscillium building.

Thanks to the mirror world's disregard for the landscaping of men, I quickly find a tree with long, sweeping branches. I climb up slowly, trying not to break the veins covering the tree, but failing. I'm still not sure how this world works, but my best guess is that the Dread and this world are interconnected: all part of one big ecosystem, driven by fluid veins rather than the cycle of decay and rebirth that governs what I still think of as the real world, despite all frequencies of reality being equally real.

I slide down the branch. It bends under my weight but keeps me above the buzzing fence and deposits me gently on the other side. I lie on the ground, facing the woods, and slip out of the mirror world long enough to give Maya and Allenby a wave and let them know I am past the fence.

Free of interference, I run through the mirror-world swamp toward Neuro's oscillium sh.e.l.l. I pause at the bottom, considering what I'm about to do. It's a desecration of the dead, but maybe the Dread won't see it that way? I have no way to find out, and I don't think any of them are around to see this anyway. Stepping inside the matriarch's remains, I scale the side of the building, using her ribs and spine for hand and footholds. At the top, I turn toward the monster's ma.s.sive skull. The tendrils are gone. The eye sockets empty. But the holes in its skull, created by the 20 mm rounds I fired, remain. I say my apologies and head on my way.

The ruined elevator shaft grants me entrance beyond the oscillium shield, and I quickly make my way inside the building, moving through the interior while in the world between. With my memory returned, I have no trouble locating the nearest security room. There's one on every floor. Looking into both worlds, I keep watch on the security guard seated in front of a group of monitors. The screens are alive with movement. Rooms are crowded as scientists, a.n.a.lysts, and men in black suits comb through and inventory everything. It's possible some of it has already been moved off-site, especially the data. There's nothing I can do about that, but I can stop them from getting any further.

Standing behind the guard, I send a pulse of fear into him. He twitches, looks around the small room, and writes it off. I give him a second, more powerful dose. He gets to his feet. Reaches for his gun-standard-issue. No oscillium. These guys have no idea what they're up against yet.
