When Calladia Cunnington saves someone from a demon attack one night, she's happy to put her magic and rage to good use . . . until she realizes the man she saved is none other than Astaroth, the ruthless demon who orchestrated a soul bargain on her best friend. Suffering from amnesia, Astaroth doesn't know why a demon named Moloch is after him, nor why the witch who saved him hates him so much. The two set out to find the witch who might be able to restore Astaroth's memory so they can learn how to defeat Moloch. The more time she spends with the snarky yet utterly charming demon, the more she realizes she likes this new, improved Astaroth . . . and maybe she doesn't want him to recover his memories, after all.
