Demon in Steam

In the shadowy depths of the London Underground, the Alliance of Silver and Steam stands as humanity's defense against demons. Felicia Ganon, driven by a thirst for vengeance after witnessing her parents' murder, has been trained by the Alliance to combat these sinister beings. When a murderer threatens the fragile peace, she finds herself reluctantly paired with Greyston Westham, a strikingly handsome captain of the Guard and an Incubus Demon himself. As they navigate their deadly mission, Felicia must confront her deep-seated hatred of demons and decide whether to embrace a relationship that could be her salvation—or ultimately lead to her doom.
