Lots of hot sex, with both secret fantasies of the heroine that she has written on her laptop. and the actual sex of the hero and heroine. And, after he steals her laptop, he is able to read all her fantasies and help her act our some of them, though she at first resists, especially when they must go to a BDSM club to receive a cure for an infection she receives from an infected vampire.
The heroine has perfected a formula for synthetic blood that would also help the vampires "come out" and show humans that they can be trusted not to feed on them. And with a conference coming up that the vampire community will vote on the nu-blod and coming out, the hero wants to convince the heroine to give up her formula. But when she is kidnapped the vampire hero will have to decide if her life or his dream of coming out is more important.
And this is one of the only vampire books that I have read that addresses the fact that different blood types are not compatable, and how these vampires account for that fact, and why there are not more vampires running around in the world.
