When demons threaten London, Lady Belinda answers the call.

Lord Gabriel Thurston returns home from war to find his fiancée is not the sweet young girl he left behind. She’s grown into a mysterious woman who guards her dark secrets well. When he sees her sneaking away from a ball, he’s convinced it’s for a lover’s rendezvous. Following her to London’s slums, Gabriel watches in horror as his fiancée ruthlessly slay a man.

Lady Belinda Carlisle’s only concern was her dress for the next ball—until demons nearly killed her and changed everything. A lady by day, and a demon hunter by night, she knows where her duty lies. Ending her betrothal is the best way to protect Gabriel from death by a demon’s hand.

Gabriel soon realizes, like him, Belinda has been fighting for her country. He joins in the fight, determined to show her that their love can endure, stronger than ever.
