Ten years after Alex and Aaron Stowe brought peace to Quill and Artime, their younger twin sisters journey beyond Artime in the fifth novel in the New York Times bestselling sequel series to The Unwanteds, which Kirkus Reviews called "The Hunger Games meets Harry Potter." Artime is at war. Led by the reckless new head mage, Frieda Stubbs, and swayed by her stoking their fear of the Revinir's return, the people of Artime have turned against the Stowe family. Aaron and his allies are captured while Fifer is left exposed to mortal danger. Thisbe and the team of black-eyed children from Grimere journey to Artime to help, leaving Dev behind to fend for himself against the increasingly powerful Revinir. Thisbe grapples with guilt and worry from multiple directions as her relationship with Fifer continues its downward spiral. When things are at their bleakest and everything is on the line, Fifer is forced to make a decision that could change her destiny forever.
