I am looking for a paranormal erotic romance book with a similar relationship dynamic and forced seduction theme. I would like the heroine to be an ordinary human for the most part, with no special powers but some actual form of agency that requires at least some authorial work. The hero should be supernatural, and as long as he's not something un-sexy like a mermaid or a werewolf, any older, immortal being will do. Vampires and aliens are preferable. Thanks!
