When she found her twin, Lark, held captive for three years and forced to power the magical realm with her imagination, Nix offered herself up in her sister’s place.

Back home, her uncle and boyfriend desperately plan a rescue. But Lark, having learned Nix was meant to be the Goblin King’s captive in the first place, resents how her twin stole everything belonging to her during her absence. Worse yet, Lark harbors an unspeakable secret that could destroy what little she has left.
