Seven innocents have been brutally murdered in Los Angeles, yet the Shadow Alliance has no suspects and no leads. As the body count mounts, the age-old feud between vampires and werewolves threatens to explode. Lissa Monroe--a strong-willed, ravishing succubus who entices men to surrender their souls--agrees to go undercover for the Alliance. Her mission: infiltrate the mind of werewolf leader Vincent Rand, a ferociously alluring enemy who exerts a powerful hold over her. As the City of Angels teeters on the brink of apocalypse, these two adversaries must join together in order to survive an even more lethal enemy hidden in plain sight.
