Seventeen-year-old Carter Simms has been chosen to compete in Wonder. He knows it’s an honor. He also knows that failure has a price—a one-way trip to Oblivion. The only bright spot is his flirty best friend will be in Wonder with him, and with her, the promise his summer will be anything but predictable.

Then Carter discovers Wonder is not all it seems. There are disturbing secrets hidden behind its walls. Carter picks at the mysteries of the world he thought he understood. He tumbles in the rankings. And with the chill of Oblivion on his shoulders, Carter must choose—the truth or his friend—because he can’t have both.
