Fated lovers. Slow-burn romance. A touch that could doom a kingdom. Kiki Xochicale is a Slayer in the Demon Corps. She patrols the border along a mass of darkness that splits the kingdom in two. It's her job to ensure the demons that crawl out don't make it past her. When Kiki's best friend goes missing, everyone assumes she's either deserted or been eaten by a demon. After all, Slayers go missing all the time. But Kiki refuses to believe it. Instead, she follows a trail of clues that lead her into the heart of demon territory. What she finds is beyond anything she could ever have imagined. The shadows are home to the demons but also all the people who were swallowed up by them, including the lost Princes cursed to walk the day as demon bears and spend their nights as humans. Forced closer and closer to the bear shifter who wants every inch of her, Kiki must break the curse, or the curse will break her.
