An ambitious and magnetic novel from the New York Times bestselling Neal Shusterman, about a teenage American football player forced into a series of a parallel lives.

Ash is used to taking hits on the field for his high school football team – until he takes one that doesn’t just impact his body, but his whole reality. It starts with one small shift, but with every game, every hit, Ash finds himself pushed through a succession of universes almost-but-not-really like his own, until the small shifts in reality become significant shifts in Ash’s own identity.

As Ash experiences life from other perspectives, he starts to question the world he thought he knew, as well as the ones he finds himself catapulted into. For better or worse, the one thing Ash knows is that he’s got to find a way to put things back. A searing exploration of race, gender, sexuality and the nature of privilege.
