Garrison, the main character, is coping from the death of his father. He has just started high school with his friends, Brandon and Will. While they are in class, Garrison cant stop thinking about what he saw that morningmen loading a van with guns. Suddenly, he hears marching footsteps, then silence. All he hears is ticking, and before he realizes what it is, an explosion throws him across the room, killing half of his class. The leader of the hostile group, Julian, awakens the other survivors and makes himself clear that no one is coming for them and that they wont hesitate to kill them. Garrison and his friends take it upon themselves to escape with as many students as they can find. But there is something Garrison doesnt know about himself, and he intends to find out what it is, even if he must cross a line he cant come back from.
