Grenade

"Hideki lives with his family on the island of Okinawa, near Japan. When World War II crashes onto his shores, Hideki is yanked out of school and drafted into the Blood and Iron Student Corps to fight for the Japanese army. He is handed a grenade and a set of instructions: Don't come back until you've killed an American soldier. Ray, a young American Marine, has just landed on Okinawa with his squad. This is Ray's first-ever battle, and he doesn't know what to expect -- or if he'll make it out alive. He just knows that the enemy is everywhere. Hideki and Ray each fight their way across the island, surviving heart-pounding clashes and dangerous attacks. But when the two of them collide in the middle of the fighting, the choices they make in that single instant will change everything."--.
