Secrets are nothing new to the president's son. But when a mysterious assassin attacks 13-year-old Henry Miller, he uncovers a strange power: the world slows down while he speeds up--stronger and faster than he's ever been. Trouble is, Henry can't seem to talk about it. Literally. Or make this strength happen at will. Which means that when he uncovers the even bigger plot against his father, all he can count on are his non-existent athletic skills, his best friend Lucy, and his nemesis, Reylin.
