The mind-bending conclusion to the Twinmaker series, perfect for fans of the Uglies series, from #1 New York Times bestselling author Sean Williams.

Clair's world has been destroyed—again. The only remaining hope of saving her friends is for her and Q to enter the Yard, the digital world of Ant Wallace's creation. The rules there are the same as those of the real world: Water is real; fire is real; death is real. But in the Yard there are two Clair Hills, and their very existence causes cracks that steadily widen.

Getting inside is the easy part. Once there, she has to earn the trust of her friends, including the girl who started it all—her best friend, Libby. Together they must fight their way through the digital and political minefield in the hope of saving the world once and for all. And this time Clair has to get it right . . . or lose everything.
