A very different kind of book than its predecessors _Jumper_ and _Reflex_. The protagonist is Cent, daughter of David and Millie, and it's the story of how she deals with her ability to jump, in the context of an American High School. (I'm not a fan of the American High School as a setting.) The threat level is much lower than in the first two books, and it doesn't ask any big questions about the potentially world-shaking impact of the emergence of jumping. It's small-scale; it's cozy. It's a pleasant addition to the series, but it doesn't make me want to thrust it into people's faces like the first two.
