The King of Clubs, Vol. 1 by Savannah Skye

Ursula Lee hates vampires. In fact, she’s dedicated her life to ridding the streets of the worst of them as a bounty hunter. So when she’s summoned to vamp-infested Lundercity by the King of Clubs to discuss a recent rash of murders, she agrees, in spite of the location. If someone is killing humans, it’s her duty to stop them, no matter the risk. But heading into the very bowels of London where the true sun never shines in order to face off against a creature known as Ripper?
Might be her biggest—and last—mistake.
