It starts out as a normal day at eleven-year-old Jimmy's house. Then the doorbell rings, and the two men who are standing there say, "We've come for the boy." Jimmy runs from the danger and finds himself to be capable of incredible things he could never do before. When he jumps through glass, he doesn't bleed. In fact, when he runs to his friend's house and gets a knife out of their kitchen drawer, there is no blood when he stabs himself in the arm. What is happening to him? Who is he? Why are these people chasing him?
