Oil meets water. Cat meets dog. That's the best way to describe the relationship between Sara, the Queen of Hell, and Marshall, the King of Heaven. Originally forced into marriage to end the brutal conflict between Heaven and Hell, Sara immediately assumes that there's no way she'll actually fall in love with Marshall. Not only is he barely of age, but he is much too sweet and submissive for her fiery personality. Yet Marshall persists in worming his way into Sara's heart, doing his absolute best to dote on her and get to know her better. And despite interference from Sara's jealous ex-fiance and Marshall's scheming older brothers, Sara becomes slowly (and awkwardly) attached to her puppy-dog of a husband. Will the Queen of Hell learn to love Marshall in his entirety, despite her heart of ice?
