Odd little book. The blurbcraft I saw for this book all called it a paranormal romance, but that really isn't right. It's more dark fantasy or Gothic, like Interview with the Vampire period Anne Rice. The plot concerns a Cruxim, an angel like being that hunts vampires. The novel takes place over the 16th and 18th Centuries, and our cruxim is a man of his time, convinced of his righteousness and utterly bought into the virgin/whore dichotomy.
Which is what makes this so not a romance, because when his now adult ward throws herself at him, begging for him to release her from the nunnery so she can marry and have a life, he completely freaks out. Like oh my God you can't want to have sex you slut! Then of course when he runs off like a big idiot his ward is deflowered and turned into a vampire OH MY GOD THE IRONY.
It's first person, and there isn't much authorial commentary on this, which makes the whole thing interesting indeed. The prose is overheated and formal, which I completely adore for the right subject matter, e.g. tortured angel morality tales. Oh, and there's a sphinx character who is the most impressive mix of sinuous sexiness and alarming bestiality. Bravo.
