Lucifer doesn't have time for romance. He's been ousted as King of Hell. After escaping his chains, he retreats to lick his wounds and plan his revenge. The original sinner takes on the guise of a bakery owner, ready to pass the time until he can retake his throne. Lexi Sutton, a witch with mischief magic, only wants to live a normal life with normal relationships. The problem? Getting through dates without her chaotic magic going haywire has proven impossible. She's ready to give up on ever finding love. When Lexi hears about a job opening at a new bakery, she goes for it. How could she know resisting the charms of the panty-melting owner would be so difficult, or that giving in would kick off a chain of events that destiny had been waiting thousands of years to unleash? Will Hell's number one Devil heal her heart, or will finding out his secret identity shatter it?

Lucifer never thought love could burn more than Hellfire. Boston’s newest power couple, Sam and Lexi, are trying to find a balance between their relationship and the looming war that threatens to consume them. Dealing with threatening gods and running a bakery together is putting a strain on their otherwise happy relationship. Add in the chaos brought by the queen of monsters, aka Sam's former girlfriend, and you have a recipe for a disaster. But Lexi has a few tricks up her sleeve to make sure their love survives the devil's ex and the threat of apocalypse, and she's determined to make it work. Maybe she can count on her father, Loki, for help.

They stole his heart, and now there’s Hell to pay. Abaddon made a grave mistake when he went after Lexi. Now her father, Loki, has a plan to win Lucifer a powerful ally that could help get her back. But not all is as it seems beyond the bifrost, and the time for a reckoning has come. Meanwhile, Lexi finds allies in the unlikeliest of places and discovers connections she never imagined. While she carves a path through the nine circles of Hell, she learns more about herself and the icy magic that’s been haunting her for weeks. Lucifer and Lexi are worlds apart, but their bond is strong. Will it be enough to survive what’s coming, or will Lilith finally succeed in tearing them apart permanently?
