Henry will do anything to save his father. Even if it means keeping secrets. Big ones. Thirteen-year-old Henry Miller knows he’s not typical. And it’s not just because he’s the president’s son. When a mysterious assassin attacks him after school, Henry uncovers a strange power: the world slows down while he speeds up—stronger and faster than his short, stout body has ever been. Trouble is, Henry can't seem to talk about it. Literally. Or make this new strength happen at will. If he could, he might be able to help some people, and to be seen as his own person instead of just a politician’s kid. Instead, he’s stuck navigating the daunting world of White House ushers and antiques, maids and security. As if that’s not enough, there’s his fancy new school with its formidable principal and the senator’s snotty daughter. In the midst of it all, Henry feels a little lost and a lot useless. Until he and his best friend Lucy uncover a plot to assassinate his father. But the closer Henry gets to finding the assassin, the more he begins to wonder if it’s really the president at stake. Or is his father just a pawn in a chess game where they need to find the king?
