A Vile Season

Bridgerton meets The Bachelor in this queer regency romance of a vampire competing for the heart of a duke.
After being run out of his castle by vampire hunters, Count Lucian encounters the god of vampires, Vrykolakas, while in hiding. Unhappy with how many vampires have been bested by hunters, Vrykolakas gives Lucian a test: Infiltrate the future duke's marriage games as a suitor and uncover the clandestine vampire hunters Vrykolakas suspects lurk in their midst. The god strips Lucian of his immortality so he can walk amongst mortals—making him human for the first time in centuries. If Lucian succeeds, Vrykolakas will make him the most powerful vampire in existence, but if he fails, the god of vampires will torture him for the rest of his life.
Unfortunately, Lucian isn't prepared for the emotions that come with humanity, nor the treacheries of courting season with fellow nobles posing as friends, enemies, and wholly unsuitable romantic distractions. To win the life he wants, Lucian will have to decide if being a vampire is worth giving up the friendship and love he's found.
