in the netting at the back of his chair, and Sam tries, telekinetically, to turn the knob on the tank and cut off whatever gas Ethan needs to survive. But it doesnât work. The opposite happens: the professor brings Ethan over.
âSpace for one more?â the professor asks, and they make room reluctantly. Ethan lays out his lunch in his lap: a baloney sandwich and chips. Sam can hear little puffs of air jetting up Ethanâs nose.
âDo you have AIDS?â Irwin asks.
Ethan sighs. He does not have AIDS, he says wearily. His lungs donât work right. Heâs on a list, and if his name comes up, theyâre going to cut him in half and give him new ones.
âCut in half, like side to side or top to bottom?â Sam asks, and Ethan places finger at the notch at the base of his throat. âFrom here,â he says, drawing his finger down his shirt to his stomach, âto here.â
âLungs from a dead person?â Irwin asks. â Awesome .â
Ethan turns to Sam and kicks him gently. âWhen we get back, I want you to attack Russia.â
This is just what Sam was afraid of, that heâd become another small thing in a game played between people. He just wants to be ignored, the way he spent the entire basketball seasonâon the bench, whispering multiplication tables, praying for armpit hair. Sam balls his tinfoil into a hard nut. âWhat do I get if I do what you say?â
Ethan says, âYou get to die for a reason.â
On the last morning of the world, light breaks over the ocean and Sam is there, on the beach, in Guam. The people of this island nation make necklaces from shells or eat donuts, whatever they do. But the beach is all his. Samâs father and mother lounge on the big towels, talking like they havenât talked in a long time, like they want to keep talking. Sam pokes at a dead sand crab, a weird piece of armor the ocean threw up. He is tucked between his parents, feeling gathered and protected, when he sees the white contrail of a Centaur streak up, a fast and terrible rip in the sky . . .
Sam holds a matchstick in his fingers.
His missile, the one from Ethan. His turn.
âSomebodyâs going to win this war,â the professor says, pacing behind them. âWho is it going to be? Is it going to be you?â
Across the map, Ethan nods at Sam privately, the way a gangster in a movie cues an execution. Sam has no strategy. Heâs afraid that Ethan, up in his throne, has unspeakablepowers, the gift of knowing that youâre only alive because somebody else died. But with the matchstick in his grip, his Centaur, Sam sees his life from above. Suddenly the map, the game, doesnât matter. Sam can be Guam, the speck in the Pacific, the small thing passed between people.
Or he can be the missile.
He arcs the match over the ocean, toward America. He aims for Ethan, for home. When it lands, Ethan whispers, âWhat are you doing?â and Irwin makes the blowing-up noise, a rumble with puffed cheeks. The professor says, âFirst strike. Guam against U.S.A. Interesting . . .â Soon, every missile on the map will launch, the planet turned to stone, the lesson lost. But Sam is, already, elsewhere.
That night, Momâs new friend Latrice reclines on the couch, smoking languidly and turning Samâs photo cube over in her hand. Itâs all vistas of his father: grilling, up a ladder, holding Sam at birth when he was still jaundiced and Chinese-looking. Sam recognizes Latrice from the Unitarian church, from the part of the service when people stand up and speak. Latrice talked about womenâs rights and black people rights and coming together for a better tomorrow and Mom clutched Samâs hand. Latrice is the only black person there, so itâs like she is all black people.
âYour father looks like a nice fellow,â Latrice says, and sets down the cube. She pulls her denim jacket tight. Her hair intimidates
