"Damon Cross doesn't accept resignation letters. He demands a marriage certificate." Claire Bennett survived three years as the "Devil's Secretary" to Obsidian City’s most cold-blooded billionaire, Damon Cross. On the day she finally drops her resignation letter on his mahogany desk, she catches her boyfriend in bed with another woman. Stripped of her home and her dignity, Claire is at her lowest—until her icy ex-boss steps in with a ruthless proposition: Become his fake wife for one year. In exchange, he will help her destroy everyone who hurt her. But playing house with the Devil comes at a steep price, and Claire might just end up selling her soul.
