I really can't decide on giving this 4 or 5 stars. Like I have read in other reviews, I agree that this started out pretty slowly and different. It is a paranormal romance, without juicy love scenes. Sooooo... imagine almost 600 pages of a paranormal book with maybe only 3 or 4 make out scenes and no sex. Kinda different than the books I usually read, lol. And, although there was plenty of action, it wasn't predominately an action/thriller in my opinion. 600 page - not much making out, some action and what else? History. I enjoyed this book, which totally made sense written by a historian. It could have been super boring and, although it was not a fast read, it was quality. The story line and depth was unique in this genre. I absolutely will read the next book that comes out (when I have a full 3 or 4 days to devote to reading it). I look forward to the continuation of the series.
