This was a fun, quick read with enjoyable characters and an engaging plot. My one real peeve was the infodump at the beginning that had the heroine breaking out of story space and talking directly to the reader. It yanked me right out of the story. I know that in a short paranormal a lot of information about the world needs to be transmitted quickly, but asides to the audience from the heroine do not work for me.
There were a couple of quite vulgar things the hero says early on that made me throw up a little in my mouth, and I realise that was the point but for me it was ott.
Aside from that, quirky characters and an interesting interpretation of Lucifer made this one I read in one sitting and, on the whole, thoroughly enjoyed.
