Sin City. Las Vegas. A city of pleasure where life is always a gamble. A series of killings has Las Vegas and its infamous Strip on edge. When the killer's signature mark points to an angel presumed dead, two of Fate's Guardians, mated Archangels Raphael Moremison and Gabriel Everardson, are assigned the task of bringing the killer to justice. Khari Khalidh has finally achieved her dream to be one of Lucifer's Guardians. However, her new assignment poses some challenges. Two sexy challenges to be precise. Raphael, her ex-lover, and his life mate Gabriel are her bosses. Fate has never played favorites until Raphael, Khari, and Gabriel discover they are all life mates, and there is a complication... The serial killer the Guardians are hunting—Khari's ex-lover. The angels quickly find themselves in a cat and mouse game, hoping to catch her before she strikes again. The stakes have never been higher, and love might not survive the final roll of Fate's dice.
