Slightly confusing if you've never read this series before. If the word "succubus" hadn't been in the title I might've been completely lost. I'm going to assume the man that bit her was a vampire but I'm not certain because I'm not sure if he broke the skin. Anyway, how a vampire bite makes one a succubus, I don't know. Seems rather silly to me. There'll be hundreds of succubi around in no time.
