In a world where bloodthirsty vampires roam the night and street-corner psychics have real powers, bodyguard Celia Graves always thought she was an ordinary human-but that was never true.  By ancestry, she's half-Siren; a vicious vampire attack has turned her into a creature who finds sunlight painful and must take all her food in liquid form-but who still possesses a human heart, mind, and soul. Her bodyguard business is booming: who wouldn't want to be protected by a sexy woman who is half-vampire, half-Siren princess, and a crack shot?  Unfortunately, it looks like Celia may have little time to enjoy her new-found fame.A rift is opening between the demonic dimension and our own, threatening to set hell's denizens free (including the demon personally bent on destroying Celia).
