Enter the world of the Immortals, where vamps, shifters, demons, witches, and Immortals warriors exist, and the forces of life magic and death magic struggle for balance. Amber has never heard of the Immortals-ancient warriors come to the aid of those in trouble, summoned by the Calling spell. She only learns about them when one crashes into the deserted warehouse where she’s fighting the demon who murdered her sister, and proceeds to beat back the demon. Adrian, the oldest Immortal, is intrigued by the lone young woman trying to face an ancient demon, an Old One. He saves her life, and takes her home, wanting to know more about her. He discovers that Amber’s sister had found Adrian’s brother, Tain, lost for seven hundred years, and has left clues as to where to find him. Adrian tries to leave Amber behind, out of danger, as he searches for Tain, but Amber sticks to him, needing to know the truth about what happened to her sister. She’s also drawn to this hard-edged man in the leather coat, who looks more like a biker than an ancient warrior, and finds herself falling for his dark eyes, warm voice, and incredible magic. Together they begin their quest, traveling to Los Angeles to consult with a vampire master and a dragon, then into the wilderness to continue the search. But they discover that their quest goes far beyond finding Tain-the problem touches the edge of a greater plan that puts the entire world in danger. Only the Immortals-all of them together-can hope to stop it.
