For a Few Demons More — Kim Harrison

Despite dating one vampire and living with another, Rachel Morgan has always managed to stay just ahead of trouble . . . until now.

A fiendish serial killer stalks the Hollows, claiming victims across society, and the resulting terror ignites a vicious Inderland gang war. And while the ancient artifact Rachel is hiding may be the key to stopping the murderer, revealing it could also create a battle to the death among the numerous supernatural races that live in and around Cincinnati.

For every action has its price, and when the vampire master Piscary is set free and the demonic Algaliarept dares to walk openly under the sun, even Rachel Morgan can't hide forever.
