Not part of her cracktastic Dirk & Steele series, this novel is part of someone else's series but stands on its own and is actually rather less cracktastic, featuring vampires and werewolves (plus a demon ex machina) rather than mermen, the Ferie Queen, organleggers, and gargoyles.
Keeli is a pink-haired werewolf with anger issues; Michael is a 300-year-old steppes nomad vampire executioner of vampires. Together, they fight crime!
I don't have a ton to say about this, but I enjoyed it. See it on Amazon:
