Alex has spent the past one hundred and fifty years as a Vampire, and as impossible as it had seemed, he finally found a second chance at love. Gabrielle, the spitting image of his long deceased wife, gave him a renewed sense of life and humanity. But Gabrielle isn't exactly human herself; she's half Angel. Their meeting wasn't by chance, and love is not the only thing they were destined for. After Gabrielle is attacked by a jealous Vampire and her ex boyfriend is killed in a freak accident only to be miraculously brought back to life, other darker forces come to realize Gabrielle's existence - and possible potential. Samael, one of the most powerful Fallen Angels, has set his sights on her. As Alex fears losing the love of his life all over again, he does everything in his power to keep her safe, but ultimately Samael leaves Gabrielle no choice but to sacrifice herself to protect everyone she loves. Now Alex must put his faith in the hands of both Angels and Demons alike in order to save her.
