"My name's Kate Kane, and when an eight-hundred-year-old vampire prince came to me with a case, I should have told her no. But I've always been a sucker for a femme fatale."
Kate Kane is a private eye who has been hired to investigate the murder of a werewolf just outside the Velvet, the nightclub owned by her girlfriend, the vampire prince. Her investigation sees her dragged into a war between the vampires and werewolves of Britain, with faeries, a living statue and a celibate incubus thrown in for good measure.
This is the first book in the Kate Kane, Paranormal Investigator series. It's a little like Laurell K. Hamilton's Anita Blake books might have been if they had had a lesbian hero, were set in Britain, and were funny. There's some nice world building, cool monsters, playful digs at the tropes found in other urban fantasy and mystery novels, and a bit of woman on woman action. Don't take it too seriously, just sit back and enjoy the ride.
