PR Queen Elena suffers a devastating betrayal on her wedding day. Her fiancé Julian poisons her father to seize her family’s conglomerate, then stages a car crash to kill her while she’s still in her wedding dress. Bleeding and desperate at a rainy crossroads, she’s approached by Kaelen — a blind drifter with a black silk ribbon over his eyes, who makes her an offer. To claw her way back into high society and take back everything that’s hers, Elena signs a devil’s bargain. She hires him to pose as her fiancé, thinking she’s just gotten herself a brute shield to fight her battles. She has no idea this man is The Devil — the legendary, undefeated retired assassin, a godlike force in the underworld. But the bargain comes with a deadly countdown. A black mandala curse is burned into her chest: the more Kaelen unleashes his overwhelming, inhuman power to protect her, the deeper Elena falls in love… and the faster her life drains away. As Julian closes in with elite assassin Seraphina, and her brother Elias is pulled into the crossfire, Kaelen abandons his original mission. He falls for Elena, shattering his own power seals over and over to keep her alive — only to speed her toward her end. When she falls hopelessly in love with the devil she summoned, will she claim her vengeance… or fall into the abyss of death?
