Nix and Clarey search for Nix's uncle in the parallel world Mystiquel, where Nix discovers there is more to her family curse and otherworldly artwork than she ever imagined-and unless she can solve the Goblin King's maze before the clock strikes midnight, the curse will claim more lives. Phoenix "Nix" Loring knows her family is under a Halloween curse. When she was three, her parents died on October 31st; eleven years later, her twin sister Lark suffered a similar fate. Nix battles survivor guilt; she can't even find comfort in Clarey, Lark's boyfriend and the one person who understands her pain. All that remains are her sketches, where she finds solace among the goblins and faeries in her imaginary world of Mystiquel. When her depression starts affecting her ability to see color Nix all but gives up on her art. When her uncle goes missing on Halloween day, Nix and Clarey follow his trail-- and step through a portal, becoming trapped inside a decaying version of their town filled with Nix's own sketches come to life. -- adapted from jacket
