Things have changed for seventeen-year-old Zoe ever since the dramatic events that brought her together with the mysterious X. In order to save Zoe and her family, X did the unthinkable--he traded their freedom in exchange for his captivity in the Lowlands forever.
But being back in the Lowlands has its advantages. It gives X the chance to discover his past, which could be the key to breaking the Lords' hold on him forever. Little does X know that Zoe has her own plan to reunite with him . . . one that risks her life and brings her perilously close to losing all that she and X are fighting for.
Gripping and full of heart, this epic continuation of Jeff Giles' series--which already has rave reviews from Oscar-winning director Peter Jackson and New York Times bestselling author James Dashner, among numerous others--will bring readers right to the edge of everything.
