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.
