"The conceit behind Shusterman's latest is truly unique. While it exhibits the author's usual storytelling aplomb, it also manages to delve into more serious and timely subject matter, such as racism, sexism, and homophobia. Despite these heavy topics, the story still moves at a lively pace and, thanks to a zany sci-fi twist, manages to pack in a few laughs as well." --Booklist

All it takes is one hit on the football field, and suddenly Ash's life doesn't look quite the way he remembers it.

Impossible though it seems, he's been hit into another dimension--and keeps on bouncing through worlds that are almost-but-not-really his own.

The changes start small, but they quickly spiral out of control as Ash slides into universes where he has everything he's ever wanted, universes where society is stuck in the past...universes where he finds himself looking at life through entirely different eyes.

And if he isn't careful, the world he's learning to see more clearly could blink out of existence...

This high-concept novel from the National Book Award-winning and New York Times-bestselling author of the Arc of a Scythe series tackles the most urgent themes of our time, making this a must-buy for readers who are starting to ask big questions about their own role in the universe.
