What perils await on the other side of the veil? In the seventh year of Áed's reign, night descends on the autumn festival. But a time of revelry turns into one of fiery destruction-as fae pour across the veil and the Gut becomes a battlefield in an otherworldly war. Determined to protect his kingdom and the people he loves, Áed finds himself catapulted into a realm as unfamiliar as it is dangerous, where magic is king and wild courts vie for supremacy. While the faerie Queen's missing consort holds the key to life and death, tenuous alliances raise questions about Áed's connection to the mysterious Bone court. His survival hinges on cunning as much as illusion. On a mission like no other, only one thing is certain: no one will survive unscathed.
