"Evolving. Like us. Trying to understand. But mostly hiding from men like you. And me. We're as monstrous to them as they are to us."

He stares at me, one eyebrow c.o.c.ked slightly higher than the other. "I am far more monstrous than you know."

A flicker of red illuminates his skin from the inside. He leans down so our faces are inches apart. "Everything you think you know is wrong. The Dread will not destroy both worlds. This will be a conventional war, and which side of the mirror do you think will win that fight?"

"You're wrong. I've seen it."

"When I destroy this colony, the control it exerts over the others will be severed. All of the Dread and colonies connected to this one will be lobotomized. You've seen it for yourself. How can the Dread hurt us then?"

"Preemptively," I say. "How long do you think it will take the Dread to push the world into nuclear war. Minutes? My bet is on seconds. You haven't seen what they can do. Not like I have."

Lyons shakes his head. "You're grasping. Weak. You shame yourself. The time for action has come."

"Is that why Katzman has a microwave bomb strapped to his back?"

He pauses to glare at Katzman, but the man doesn't notice. He's too busy looking at the silent Dread surrounding us. Lyons turns back to me, black smile returning. "If the big one doesn't come out to say h.e.l.lo, we're going to burn it out. We are not simply here to destroy, Josef. Today is our D-day. We are here to invade. And the best way to start an invasion is to kill the leadership. You know that. Then I'm going to wipe out the resistance, capture the weak, and turn the young against their own kind. They started a war with humanity, and now they're going to truly understand what that means. I'll destroy this place if it comes to that, but you and our enemy have underestimated my true intentions."

The full ramifications of the D-day name come clear. This isn't a simple a.s.sault, it's a beachhead into the Dread world, the first step of an invasion. "What about Maya? She'll be killed."

He glances toward Maya, his face softening a touch. "She has been dead for a long time. She is now as lost as you. I can see it in her eyes, just as I see it in yours. Death will be a mercy." He turns to his men. "Kill him."

I raise my hands as Lyons takes a step back. The men hold their fire for a moment. They probably didn't count on shooting a man with his hands up.

"Are you there?" I think, hoping the matriarch will hear my thoughts.

Whispering fills my head, much of it beyond my comprehension, but a single line is for me. "There is a natural cavern sharing this s.p.a.ce."

"Get Maya out of here, please," I reply, and glance at my wife as though to say good-bye. "Thank you," I think to the matriarch as Maya is whisked away by a bull. It retreats toward the archway on the far end. She's safe. For now.

Me, on the other hand, not so much.

Lyons loses his patience. "Kill him!"

I slip into the real world and dive to the side, but it's unnecessary. The men and their weapons have shifted fully into the Dread frequency of reality. Their bullets can't reach me here.

And then, in a flash, they can. Five Dread Squad men wink into reality. I see them for a moment as they pop into the darkness, but then I'm blind. Rather than fight in the dark, I let my vision slip into the world between. Luminous veins, some as thick as a man, cover the walls. "You don't have to do this. You can still walk away." But then the five men, who must have also adjusted their vision, take aim and fire.

The bullets pa.s.s through empty s.p.a.ce. At least, I'm a.s.suming they do. I'm no longer there. I've slipped back into the mirror world, taking a soldier by surprise.

I don't know who these men are or whether they have families or children who will miss them. But I do know they heard what I said: that peace is an option, that no one else needs to die. Maybe it's the drugs, or they've been brainwashed to not think, or they simply believe Lyons's Dread doctrine. I don't know. But I do know that they are still willing to threaten the safety of every man, woman, child, and Dread on this planet in service of my father-in-law. So when I act without hesitation, it's also without guilt.

The shock at my sudden appearance lasts just a fraction of a second. The soldier is already spinning his weapon toward me. But he's not quite fast enough, even pumped full of drugs. My fist finds his jaw, sprawling him back, directly into the path of a soldier pursuing me between dimensions. The falling man is nearly cleaved in two by the newly arrived soldier, who has shifted from the real world to the mirror world inside the other, destroying the matter that was the man's gut, cleaving a hole in his body just as I did the lab table back at Neuro. The falling soldier dies instantly and without a sound. The new arrival sees what has happened and screams. No one hears him, though. The chamber roils with the sounds of battle. Roaring, explosions, gunfire. Both sides have launched attacks.

I take a moment to look around, hoping to catch Lyons by surprise. But he's already moved beyond my reach, running-actually running-toward the Dread mole, which has yet to rise from the ground. A wedge of soldiers frames him, firing at everything that moves.

A second Dread Squad soldier shifts from the real world to the mirror right in front of me, spinning, a.s.sault rifle raised. Ready to put a bullet in my head. But he's too close for the a.s.sault rifle to be effective.

I grab hold of the still-hot rifle muzzle, pull the weapon out, twist it, and then slam it back into the surprised soldier's face. While he's stunned, I slip behind him and pull us both back to our home dimension, keeping my vision locked in the world between. The three remaining soldiers open fire, killing their comrade. While they continue the barrage, filling his oscillium armor with lead, I slip back into the mirror world and charge toward empty s.p.a.ce. Hoping I've timed it right, I shift back, punching.

My fist connects with a man's face. I'm back in the cavern, and then I'm not. While the punched man falls, I dive and roll through the mirror dimension before shifting again, grabbing hold of one of the still-upright soldier's weapons, thrusting it up, and chopping him in the throat. While he starts to gag, I slip out of the real world once more, move to a new position, and return home again. I'm standing directly in front of the last soldier.

My strobelike a.s.sault, slipping in and out of view, slows the man, but the drugs keep him moving.

He discards his rifle and draws a blade, thrusting it at my throat. As the tip cuts a nick into my skin, I catch both of his hands in mine. We push against each other for a moment, maneuvering the knife away from and closer to my throat-that is, until I shift frequencies again, this time taking the man's hands and the knife with me. When I shift back, the now-handless man is screaming. I silence him by turning his own hands around and plunging the blade into his heart.

Taking a moment, I flicker in and out of the world between, leaving behind the blood on my hands, not because it's gross, but because it's slippery. I recover a Vector a.s.sault rifle and several spare clips from the fallen men. I then take the headgear from the man with a knife in his chest, clutched by his own severed hands. The black mask and round goggles make me look just like one of them. Just another Dread Squad. After a quick check of the rifle's chamber, I slip back into chaos.

The colony is a war zone.

More soldiers storm into the chamber, arriving in small groups. The Dread are being reinforced from the other side. Bulls thunder across the arena, taking streams of bullets before falling to the might of men. Men who are eventually going to run out of ammunition. Mothmen descend from above, tackling soldiers, tearing into them. Others simply carry the men up and release them, letting gravity do the rest. And still others are shot from the air. They're swift, but in the enclosed s.p.a.ce, facing men who have trained to hit moving targets, they're dying more than they're killing.

A cloud of Dread bats swirls around the chamber. They're not attacking. They're panicking, swirling upward toward the ceiling and the many holes leading out. They're good for gathering intelligence, but I suspect they're closer to trained animals than to higher functioning Dread.

The two mammoths are making a mess of the human soldiers, kicking, stomping, and charging through the Dread Squad ranks. An RPG cuts across the open chamber, snaking a trail of smoke behind it. The projectile strikes one of the mammoth's flanks, detonating with a fiery explosion that sends a wash of gore over the men nearby. It also sends the remaining mammoth into a frenzy. Knowing what I do know about the Dread, I realize the two giants were probably friends. Maybe family.

An approaching buzz turns me around. A mothman descends toward me, clawed feet extended. I raise the Vector, but hold my fire and push a wave of fear at the thing while thinking, It's me! The thing swerves away, picking another target, but is shot down in a splatter of bright red.

Are my thoughts part of the whisper? The Dread whisper is now like a rushing wind. There are so many mental voices mixed together that I can't tell if there is any kind of actual communication getting through. The screaming on the human side of things isn't much different.

Until I receive a message loud and clear. A soldier punches my shoulder. "Weapons up, a.s.shole!"

He rushes past me, firing. I shoot him in the back without a second thought. Then I turn on the rest of Dread Squad, pick a target, and fire.

Pick a target. Fire.

Pick a target. Fire.

I repeat the process five times before my treachery is seen by someone who doesn't receive a bullet to the head a moment later. Bullets chew up the chamber floor, then stop when I slip between frequencies, back to the natural cavern. I start running, slipping in and out of worlds, firing at soldiers as they try to adjust to my new position. It's an impossible task. Every time I leave the mirror world, I alter my pace and course.

The confusion caused by my interdimensional counterattack distracts at least a third of the Dread Squad in the chamber. It's just a moment, but it's enough for the Dread to attack anew. Charging forward, pushing a tidal wave of fear ahead of them, the mammoth and five large bulls slam into the enemy ranks, stomping, thrashing, and swiping with claws. Some men are trampled underfoot. Some find themselves crushed by ma.s.sive bear-trap jaws. The rest are tossed about like juggling pins.

For a moment, the Dread have the upper hand.

But it's only a moment.

Two chain-fed M2 Browning machine guns, now resting on tripods, open fire from the far end of the chamber. The weapons unleash up to twelve hundred .50 caliber rounds per minute. That's like having rapid fire on the Desert Eagle and a nearly infinite amount of ammo. The thunderous roar of the two guns drowns out all the screaming, but the whispering in my head is still clear-and frantic.

As the mammoth and line of bulls are cut down and my presence is, for the moment, forgotten, I scan the chamber. Lyons is at the front line, his wedge of men now twice as long and two men thick. They're heading for the matriarch. I consider going for the machine guns, but the time it would take to reach them and take them out would mean leaving the matriarch at the mercy of Lyons. Were it any other Dread, I'd let it fend for itself, but the giant creature buried beneath this chamber is the key to life or death for our planet. If it dies, we all die.

Mind made up, I take aim at Lyons and fire a single shot, striking him in the back. He pitches forward but quickly stands upright. His armor absorbed the shot, but it should have knocked him to the ground and left him gasping for air. I should have aimed for his head. Why didn't I aim for his head?

For Maya. The man is still her father.

Lyons glares at me, oblivious to the danger around him, unflinching at the sound of gunfire, the closeness of Dread, and the fear they're pushing. Unlike the other Dread Squad members, who, despite the drugs, still flinch at the fear effect, Lyons appears to be impervious. He's fearless. And impossibly large. Powerful.

And ... glowing. Radiating red from inside.

What has he done? Whatever it is, I'm going to undo it. And him.

I peel the mask from my head, let him know I'm still alive and kicking-and coming for him. And then I wink out of the mirror world and charge toward his position.

I race through the cavern, alone except for the dead Dread Squad men behind me. The air is crisp, clean, and a welcome change from the tang of the mirror world. A distant roar reveals the underground river's outlet, which pours into the cavern, beyond my sight, no doubt flowing away, back into the earth.

Lyons had been a good hundred feet from me when I started running. If he's still pushing forward, he'll be within reach in just a few seconds. He'll be surrounded by his soldiers, too, but I really don't care.

At all.

Brief winks of light mark the arrival of the Dread Squad. Seven of them.

Not enough, I think. But then I remember what's happening in the mirror world. That he sent seven of his protectors says he realizes the danger I present. But he's still underestimating me. Had he really understood what I can do, he'd have sent everyone.

While the seven men take aim, I roar. Carried along with my voice, moving at roughly the same speed, is a whisper of fear the likes of which these men have yet to encounter. It's a gift, I realize, from the matriarch, and it's painless. The matriarch did a little more than return the last bits of my memory. While I can't feel the fear effect myself, I somehow know that it's on the level of what a Dread mole can produce. And I remember that feeling. It nearly broke me. No amount of drugs can overcome such raw, unfiltered terror.

I push it in waves, each invisible torrent crashing into and through the very souls of these men. I become their worst fears, in the flesh, rushing toward them. I'm so focused on generating this mind-numbing fear that I almost don't notice I'm also pulling the a.s.sault rifle's trigger, sending the last of my ammo into the seven men, ending their fear forever.

When the last of them drops in a heap, I stop, draw my Desert Eagle, and slip back into the mirror world, intending to put a bullet in the back of Lyons's head.

Instead, I'm met by a thick fist, driven into my gut. I stumble back, pitched over, sucking air. The handgun drops from my grasp. Bent over, eyes shut, I can't see a thing, but I know everything has changed during my brief time in the cavern.

"I saw you coming." Lyons's voice is deeper than before. Stronger. So is his punch. "You always seem to find a way to surprise me, but not this time. It's your turn to be surprised. Your turn to feel fear."

When he says "fear," a ripple of energy flows through me. He's pushing fear at me, but not hard enough. I barely feel it. Still, he's adjusting to the change faster than I did. And in ways I didn't.

He's stronger, faster, all his previous ailments repaired, and then there's the glow radiating from under his skin like ... veins of color.

Oh my G.o.d ... The refinements he made to the Dread DNA that allow a human being to sense the world like a mirror-world resident were intensified, or perhaps lessened, with his own personal batch. How long has he been changing? Did the alterations to his own DNA effect his mind? Is all of this a result of some kind of faulty rewiring? He wouldn't be the first person to have boosted aggression from a body-altering substance.

"Look at me, son," Lyons says.

Catching my breath, I crane my head up. He stands above me, looking bigger and meaner than ever. He's nearly bursting out of his armor. Thick veins pulse with red light just beneath the skin of his neck. He's becoming more Dread with each pa.s.sing second.

"I can see it in you. The fear." Lyons chuckles. "Look around, Josef. Your treachery has failed."

He's right about that. The only Dread left in the colony are dead or dying. That is, except for the matriarch, which still hasn't climbed out of its hole. Is it hiding? Knowledge surfaces, answering the question. It's rooted. The larger the colony, the older the matriarch. It's actually part of the colony, unable to rise up again, held in place by the colorful veins that feed everything in this world. If it leaves, it dies. And if that happens, the Earth dies on both sides of the mirror. The matriarch I killed in New Hampshire had been a youth, loosely rooted and inexperienced. It should have never left its colony. It would still be alive if it hadn't.

But staying hidden beneath the ground isn't going to help this subterranean behemoth at all. The Dread Squad numbers have been whittled down. A large number of the bodies littering the arena floor are human. But there are still forty of them, most uninjured, some aiming RPGs at the tendrils slowly warbling behind Lyons. Others are repositioning the machine guns on either side of the matriarch. If it rises, they'll cut it to pieces.

I am the last hope for both worlds now.

"You are not alone," says a whispering voice. The matriarch. She's still in my head. "Delay them."

I search the eyes of the Dread Squad soldiers, stopping on a familiar face kneeling down, opening a backpack. "If you set that thing off, you're killing the world."

Katzman pauses. Meets my gaze until Lyons's breaks it, saying, "Finish your job." The words propel Katzman back into action. He takes out a large black device with a black, domed top. The microwave bomb.

"We are liberating this world," Lyons says, "one colony at a time. And when they lose this colony, they'll lose control of colonies across the continent. They'll also lose control of the hundreds of millions of people they're affecting in North America alone. Don't you see what that means? Riots will end. The government will rein in control, easing tensions. We'll be saving the world. That you think otherwise is-"

"Educated," I say. "That's not how this works. The moment that bomb goes off, the matriarch will trigger nuclear Armageddon. You will destroy the world. And for what? Because you p.i.s.sed your bed every night when you were a kid? Because the big, bad Dread made noise or moved things, made you feel a little screwy in the head?"

Lyons growls and flexes his fingers. The fingernails pop off, replaced by sharp, black talons. He's oblivious to the change.

"It doesn't matter what happened in the past," I say. "Genocide isn't an acceptable solution."

"Genocide?" He laughs. "They're not even human."

"I'm not sure any of us are really human anymore," I say, motioning to myself and the Dread Squad. "Have you looked in a mirror lately? Look at your hands."

He lifts his thick fingers up, inspecting them. He flinches upon seeing his sprouted claws. He looks confused, but it's just for a moment. Whatever discomfort he feels about his physical transformation is replaced by a wicked smile. The change has got to be altering his mind, too. This is no longer the Lyons I knew. No longer the man who was Maya's father. "I am becoming more than both races. I am ... evolving."

"You're a monster," I tell him.

When he looks down at me, the sides of his head bulge, split with a slurp, and open, revealing a second set of eyes. "Monsters both."

"Sir," Katzman says. "It's ready."

"Start it," Lyons says.

"Don't!" I shout, but am quickly silenced by claws raking across my chest. The powerful and sharp-tipped hand tears the armor away from my chest, leaving faint, paper-cut-thin slices in my skin. Had I not been wearing the armor, I'd be missing my chest.

"Help is coming," the matriarch whispers in my head. "In the cavern."

Rippling energy courses through me. It's Lyons, pushing his fear, hammering it down on me like a weapon. I fall to my knees, clenching my fists, shaking and hissing through my teeth. A sob bursts from my mouth, embarra.s.singly loud.

"How does it feel? To experience fear after a lifetime of not knowing it?" Lyons steps closer, reaches out for me.

"They are ready and will follow your lead," the matriarch whispers.

"Actually," I say to Lyons, "I couldn't tell you." I turn my head up, not a trace of fear in my eyes, and smile. Turns out I'm a decent actor, though I have my short time as a fear-feeling person to thank for the authentic, trembling sob. Despite Lyons's inhuman appearance and increasing size, I feel nothing beyond the desire to beat him senseless. I didn't realize it at first, but then I picked up on the signs. Acting without thought. Disregard for bullets. A steady heartbeat. When the matriarch restored my mind, she didn't just return my memory but my fearless nature as well. "Surprise."

I slip out of the mirror world and into the real-world cavern. While I once again feel no fear, I have what might be the single largest "holy s.h.i.t" moment of my life. And then I smile.

The cavern is full of Dread crocs, all standing still, waiting.

For what?

For me, I realize. The matriarch has given me my own army.

There are at least thirty of them. Maybe more. The combined glow of their exposed yellow veins illuminates the s.p.a.ce, allowing me to see the water-smoothed floor and craggy ceiling for the first time. The nearest of the crocs, a ma.s.sive specimen, steps closer and leans its snout down. It's just a foot away. I can smell its warm, fishy breath. Had I still been able to feel fear, I might p.i.s.s myself.

I reach out and put my hand on its head. "Let's go."

I push through frequencies, stretching the fabric that separates dimensions, and then, all at once, I pop through.

And I'm not alone.

In the time it takes to finger snap twice, the tide of the battle does a one-eighty. Back in their home world, the Dread crocs spring into action, lashing out, trampling and consuming the Dread Squad. There is resistance, of course. The drugged men fire their weapons, performing a ma.s.s "Hudson" killing of some of the crocs and each other in the confusion. But the battle is lost the moment we enter the mirror world.

I'm not sure if it's purposeful, but the Dread crocs leave Lyons alone-or rather, they leave him for me. While he's still recovering from the surprise attack, I draw both trench knives, leap forward, and drive the twin, foot-long blades into his chest.
