The Lantern's Ember

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.
