I just got out of a book slump and this book was everything that I didn’t know I was looking for. There’s romance, action, drama, suspense and vampires (which if you didn’t already know, I absolutely love). The world-building was incredible and I loved that even though this was the first book that I read in the series I still understood the culture and rules of this society. “Blood Vow” has several stories combined in it. The main story focuses on two couples: Axe and Elise and Rhage and Mary. Axe and Elise have a fierce attraction between them but Axe has sworn off any kind of relationship. Also there’s the not-so-tiny problem about him being her bodyguard. On the other hand, Rhage and Mary are a happily married couple who are in the process of adopting a little girl. Their lives are seemingly perfect until a threat appears that could tear them apart (sorry, I’m trying not to spoil anything and it’s pretty difficult for me). I didn’t feel like this book had much in terms of plot. Like I expected there to be a great big evil force that everyone would come together and fight. However I still really enjoyed this book and the characters. I’m going to be following this series. I love how the characters were like a family. This is a great read for anyone who loves fantasy.
