For a Few Demons More (The Hollows, #5)

Despite dating one vampire and living with another, Rachel Morgan has stayed ahead of trouble until now. A serial killer stalks the Hollows, claims victims across society, and ignites a vicious Inderland gang war. Rachel hides an ancient artifact that could stop the killer or start a battle to the death among supernatural races of Cincinnati. Every action has its price. 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.
