I really loved this book I like how vampyrs are described and the author did a great job of explaining their history it made for a well written story. I also really liked the characters especially Jason he is interesting rushed to someone's aid and eventually end up in a world he did not know existed. He is kind and caring and would do much for those in need I also like many other characters like Cooke, Taigo, Hadrian and Ode all of them added so much to the story. I really also loved Varic he is set in his ways but willing to do a lot for Jason whom is his mate he is an overall interesting character. I also loved the side pairings that cropped up with Taigo and Hadrian and also Ode and the vampr she ends up with it adds so much to the story. The story is amazing it starts with Jason rushing to someone's aid ending up in something he didn't understand to finally finding out these things are real and diving right into that world finding his mate which was unexpected for both of them having issues because of his nature and having an happy for now ending.
