Welcome to a world where nightmarish creatures reign supreme.

Five hundred years ago, Jack made a deal with the devil. It's difficult for him to remember much about his mortal days. So he focuses on fulfilling his sentence as a Lantern—one of the watchmen who guard the portals to the Otherworld, a realm crawling with every nightmarish creature imaginable. Jack has spent centuries jumping from town to town, ensuring that nary a mortal—or not-so-mortal—soul slips past him. That is, until he meets beautiful Ember O'Dare.

Seventeen, stubborn, and a natural-born witch, Ember feels a strong pull to the Otherworld. Undeterred by Jack's warnings, she crosses into the forbidden plane with the help of a mysterious and debonair vampire—and the chase through a dazzling, dangerous world is on. Jack must do everything in his power to get Ember back where she belongs before both the earthly and unearthly worlds descend into chaos.

Colleen Houck, the New York Times bestselling author of the Tigers Curse series and Reawakened series, breathes new life into classic folklore in this wild, twisting adventure propelled by the spirit of Halloween.
