Right chemistry, the sex scenes didn't do it for me. 
 I always get confused, when the female (that's Elizabeth Pierce, or "Elizavetta" as Lothaire throatily calls her with his Russian accent), is going "No, No" in the bedroom arena, but then she capitulates with abandon and moans away. Does that mean she didn't really mean "No" in the beginning? That's the only way I can work my head around it. People who genuinely mean "No" don't end the session by moaning, and enjoying themselves - right? 
 Lothaire, is The Enemy of the Old, he's been alive for millennia, trying to seek revenge on his paternal family, after his mother's horrific murder and he does this by wanting to acquire a "chess-piece" - that's Soraya, Goddess of the Blood and able to control the Horde, possessing Elizabeth's body when she blood bonds with Lothaire certifying she's his mate. He wants to gain possession of some magical ring, that grants him any wish. Turns out Soraya is not his mate, and it's "human" Elizabeth after all. Huh. 
 What I really want to do, is read Nix's story.
