On her sixteenth birthday, Y/N expects nothing. No one in her family has ever received a demon during the Imprinting, and after a lifetime of being ignored, bullied, and mistreated by her parents, she’s learned not to hope for things she can’t have. But when the most powerful demon in existence suddenly appears before her, the world is thrown into chaos. Feared by demons and humans alike, Karn Ledger has never been called to a human—until now. As an unbreakable bond forms between them, Y/N finds herself at the center of a mystery that could change everything, while the terrifying demon king discovers there is only one person in the world he would burn it down to protect.
