Nightwalker (Dark Days, Book 1) - Jocelynn Drake
The world building was very interesting, particular the "other" hierarchy with human-hating elves being the strongest and most feared. It was unique to read a novel where the primary character is a vampire that is not at the top of the food chain. I was almost 50% through the book before I decided that I actually liked the main character. Her back story unfolds slowly but once you learn the details it is easier to understand her outlook and her behaviour. I will likely read the next in the series simply to see where the story goes.
