This is a great spooky/dark teen book that can be read in one sitting (if you can afford such a luxury). I don't know why but I've really been gravitating towards the dark fiction these days. Midwinterblood is a one complete novel but is told in varying short stories all of which take place on the same remote Scandinavian island, "Blessed", but in different time periods. The first story begins in 2073 and they gradually go backwards in time by centuries. Each story slowly reveals more and more of the mysterious history of the island culminating in the final bloody reveal. If you like the following ideas, this story might really appeal to you: isolated societies, sacrifice, vikings, archaeology, reincarnation. 
 Also, I wanted to point out, because I think this is important, that I absolutely dislike the cover of the edition I read. It is an awful representation of this book. In person, it looks a bit nicer as it has a cool holographic 'thing' over the girl's face but I think the overall look does not depict the story well as might alienate male readers. Though there is a foundational love story, I would not consider this a paranormal romance story - and I feel that is the look that the cover conveys.
