New York Times bestselling author A.G. Howard launches a dark and compelling new YA fantasy series about a girl whose family is cursed by Halloween.

Phoenix "Nix" Loring knows her family is under a Halloween curse. When she was three, her parents tragically died on October 31st. Eleven years later, her twin sister Lark suffered a similar fate.

Ever since, Nix has battled survivor guilt. She can't even find comfort in Clarey, Lark's boyfriend and the one person who understands her pain, because Nix's hidden feelings for him go far beyond friendship. 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, until her uncle goes missing on Halloween day. Hot on his trail, Nix and Clarey step through a portal, becoming trapped inside a decaying version of their town filled with Nix's own sketches come to life.

As Nix and Clarey search for her uncle within the sinister and dangerous world of Mystiquel, Nix discovers there's 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, her life won't be the only one the curse claims next.

Set in a gritty, atmospheric world filled with magical creatures, New York Times bestselling author A.G. Howard launches a thrilling new fantasy full of romance, twists, and betrayals.
