I shrug. "It was eighth grade and computer cla.s.s."

"Didn't she have braces then?"

"Oh yeah."

He shakes his head.

"How about you?" I ask.

If possible, his cheeks pinken even more.

"Oh don't tell me, sweet sixteen and never been kissed?" I mean it like a tease.

"More like eighteen," he says staring at his lap.

I feel my smile tighten as I think about the bite on his ribs and suddenly it doesn't seem so funny anymore.

It's pitch-black dark when he finally comes clean. "Listen, I gotta tell you something," he says. He must have known I was pretending to sleep because he doesn't bother trying to wake me up first.

I shift a little, feeling the boat rock slowly under my movement. We haven't seen anything else for days: no ship, land, rafts. Only so much nothing that it feels like we have to be the last people left.

As he explains I bite my teeth together as hard as possible, wondering if I can break them-break everything and be done with it.

"I'll go overboard, if you want," he says. In the darkness his voice has no body, no infection. It just is.

"But then you'll turn into one of those things," I tell him.

His breath shakes. "I'm going to turn into one of those things no matter what," he says.

I push my fingers into my eyes, trying to poke them hard enough to bring tears because it's the only way I can think of to unleash the searing pain inside. "Is that what you want?" I ask him.

"If I stay on this raft and turn, I'll go after you," he finally says. He pauses and in the emptiness our hearts keep beating. "I don't want that," he adds softly.

"So you think you can take me?" I ask him.

He doesn't laugh, not really. It was a lame joke anyway, but I do hear him exhale a little harder as if he'd thought about laughing. "You have to promise me you'll throw me over when it happens," he finally says. "Promise me you'll make me sink."

I press my fingers harder against my eyes.

"Promise me." His voice is urgent.

I shake my head. "I promise," I mutter.

"I think Nancy had a little crush on you," I tell him. It's a thick soupy day, taunting us with rain and I'm organizing our water bottles to catch what I can. My mouth tries to salivate at the thought of it, cool and wet, sliding down my throat, filling every dry s.p.a.ce inside me.

"I hope so, since she's the one who bit me." He's leaning back in the shade of the canopy, shirt off now that I know his secret. I can't look at him without glancing at the bite festering along his ribs. It's like he's proud of it, forcing us both to deal with it.

And then I realize what his words mean. "So you knew." I don't ask it as a question. I turn to face him. "If she's the one who bit you, you knew about everyone else. Francis, Nancy and the others."

"Why do you think I told you we shouldn't wait for them?" he asks. Red streaks along his skin, marking every vein through his body with an infection whose heat sometimes radiates along the rubber of the raft.

"Then why did you keep asking to go back if you knew?"

He shrugs, stares at his hands. "I wanted to be wrong. Doesn't matter now, I guess."

And he's right. We lost sight of the last raft two days ago.

His hands are hot as he grabs for me. He's gasping for breath and at first I think he's turned, gurgling on moans, but then I realize he's trying to say my name. "Get up," he says, shaking me, but his muscles are weak from so many days of disuse and I'm still much larger and stronger than he is.

"Get up," he prods again.

He shoves something into my hand, the lanyards that lashed the flap of the canopy shut. "Tie me up," he says. "It's time. Tie me up, sink me."

It's been harder and harder for me to surface from sleep and I struggle to understand what Jeremy's saying. He's wheezing now as he takes my hands, wraps my fingers around the ropes, pulls them tight along his wrists and elbows.

His skin's dry and cracked and I try to blink the salt from my eyes so I can focus on what's going on. It's dark in the little raft, pitch-black swallowing us everywhere with just the tiny hiccups of the alert beacon flashing.

-flash- Jeremy knotting the ropes. Using his teeth to tighten them.

-flash- Me winding them around his torso, tucking up his knees.

-flash- Jeremy's eyes gla.s.sy and bright. His chest barely moving.

-flash- I don't know what to say. What to do. What to tell him.

-flash- I slip my fingers into his. "I'm sorry, Jeremy."

-flash- He's nothing.

-flash- Dead eyes. Still heart.

-flash- Waves tilt and whirl as his body becomes a sh.e.l.l.

-flash- I breathe in. Hold it.

-flash- -flash- -flash- I exhale.

And before the light can flash again he explodes, straining and struggling.

I see the perfectly straight teeth, the gleaming white as he tries to lunge for me.

As he snaps at the air.

Screaming, I throw myself across the raft. Pushing and forcing myself back. Wishing the walls could absorb me. Keep me safe. His moans are like growls, guttural and wet. He's insane with what looks like agony and rage and a desire so intense I can smell it.

Beneath me the entire raft bucks and swirls, his movements teetering us around, his feet ripping at the canopy overhead as he tries to gain his balance, tries to push himself closer to me.

I can't get near him, can only watch as he pulls and pops against the ropes. Can only hear the strain on his joints, the snap of his wrist breaking apart under the twisting jolts. It's too much. I can't stand it, can't be near him anymore. Can't see him like this.

I dive through the opening in the canopy into the night, letting the waves close over my head until I can't hear, can't see, can't forget as the raft twists and shudders above me.

"Do you believe in G.o.d?" I ask Jeremy. Water pools around the divot in the raft where I'm crouching and I've pulled open the canopy, hoping the sun will burn it away so that my poor chaffed skin can find relief.

Jeremy bucks against the soggy ropes holding him tight. I've lashed him to the other side of the raft and used strips of my shirt to tie his mouth shut. He still manages to moan, deep nasal sounds that reverberate through the raft so that I'm always feeling them even when I shove my hands to my ears.

I tried to push him overboard, I swear. But I just couldn't do it. I couldn't let go of him.

He's all I have left. I couldn't drift away from him on the empty horizon.

"Blink once for yes, twice for no," I tell him, staring into his face. He doesn't blink, just tries to lunge for me, his shoulder buckling back at a sickening angle.

"Jeremy?" I whisper. It's night, pitch black, and I swore I woke up to screaming. I swore I woke up to Jeremy and his nightmares.

The raft shudders. Jeremy still desperate to escape. Still desperate for me. I shake my head, feeling like my ears are full of water, every sound distant and dull.

"Jeremy?" I ask again.

Carefully, I crawl across the raft, my muscles having a hard time keeping me from falling over. The bottom sags every place I set my hand and knee, feeling as if it too is giving up. I pull myself face to face with Jeremy, too close to be safe.

"Is there anything left?" I ask him.

And I can't tell if he's shaking his head or if he's just twisting against his ropes to get closer to me.

I'm pretty sure Jeremy's been talking to me. When I wake up I'm positive I hear his voice in my head. And when I'm staring at the horizon, trying to find shapes in the wavering distance, I swear he's saying something.

"You promised." He's starting to sag against his ropes. His body's pretty torn up, joints dislocated and his left arm fractured where he pulled too hard. His skin's tight over his face, cheekbones sharp and accusing.

"I'm not ready," I tell him.

"Neither was I," he says.

I turn away again. Nothing inside me is willing to cooperate anymore. Everything shudders and falls apart, muscles failing to fire, bones shifting under my skin so that I always hurt.

"You promised," he says over and over and over again until I almost do want to throw him over just to shut him up.

It's raining, so our water bottles are full again. One of the survival pouches has a fishing kit and I've been sitting here for a while staring at the gleaming little hook. Part of me wants to draw it along the raft, wondering if it's sharp enough to gash the boat and sink us both.

We ran out of food three days ago, so I don't have anything to use as bait. I've tried using just the hook but nothing bites. I stare at Jeremy, at the flesh flayed off his broken thumb. His moans are more like whimpers now and my stomach heaves as I pinch at his skin, tearing the little flap off.

I shove it on the hook and toss it in the water and wait, thinking of the fish circling underneath us, wondering if eating Jeremy's undead flesh will cause them to turn as well. Thinking of the feel of their meat on my tongue, the thick oily taste of it, makes me weak with desperation so intense I tremble.

Hours pa.s.s, the storm dwindles and nothing. Wincing, I close my eyes, cut a sliver of my own skin away. As soon as the scent of my blood hits the air, Jeremy explodes, thrashing harder than he has in days. Startled, the hook slips through my fingers and falls away into the depths.

I sit staring at the b.l.o.o.d.y flesh in my fingers, red and bright and wet. Inside I'm empty, nothing but water sloshing through my veins, nothing but the taste of salt coating my tongue. Slowly I raise the bit of skin to my lips and close my eyes.

Jeremy moans and writhes as I force myself to swallow.

It's dark again, so dark that nothing makes sense. There's a storm whipping around outside, dragging the raft and tossing it around. I brace my hands against the walls and try to hold on tight but still I'm thrown into Jeremy, thrust against him again and again.

Everything's soaking wet, water seeping through tears in the canopy even though I've done my best to lash it shut. It's slippery and I can't keep my balance. I reach for Jeremy's hands.

"I don't want to be alone," I scream at him, my throat raw and cracked. "I'm scared."

It's too hard to keep doing this, to keep surviving. I'm exhausted and my body's beyond pain: salt leaches into my cuts, my skin's tight and shrunken with sunburn and my stomach is so empty I'm frightened it no longer exists.

"I'm afraid to die," I tell Jeremy. His fingers grab for me, clutch on to me as if he understands what I'm saying. He seems so much stronger than I am.

I kneel in front of him and pull the sc.r.a.p of shirt from his head, unleashing his jaw. He snaps and moans, louder than the roar of the storm. My breath is shaking as I reach my arm up to him, push it toward his mouth.

A wave crashes down on us, flooding the tiny raft and in the murk of it I feel the sharp sting of his teeth closing around me.

I rest my head in Jeremy's lap and stare up at the calm blue sky. There's something comforting about him, about the feel of him underneath me like I'm a kid curled up on my parents' bed on a Sat.u.r.day morning.
