Once best friends, Arthur and Wally find themselves on opposite sides of an epic war. Arthur, now officially a Novitiate of the Wardens of Weirdwood, is tasked with defending the Veil, the border between the real and imaginary realms. But Wally and his brother, Graham, who can see into the future, seek to tear it down and create a new world with magic accessible to all.

Meanwhile, the fearsome Eraser seems unstoppable as it destroys entire pocket-worlds, all the while tearing Rifts in reality, sowing chaos, and letting wondrous and dangerous Fae creatures run wild. Will Arthur and Wally be able to put aside their differences and work together to defeat the Eraser when it shows up in their city and threatens their home? In this exhilarating final installment of the Thieves of Weirdwood trilogy, the lines between reality and fantasy will forever be broken.
