I have a hard time summarising the experience I had with this book. I guess that's what a three star experience is: It was fine but not remarkable. 
It was hard getting into this world. I hadn't read such a werewolf heavy story before and it was a struggle at first. I grew more into it as I went though. I can see how you would get attached to this series. The found family in this is strong with interesting characters that give space for exploring.
What I struggled with most was the age gap. For most of this book the gap is icky and weird, because Joe is so young. The fact that they met as kids just doesn't sit right with me. The possessiveness of their relationship also wasn't my taste. It was just too much. This book really focuses on their relationship, so that's a big chunk of book that I have uneasy feelings about.
Will I read more? I'm not sure to be honest. While curious I also think there are other books I would rather spend my time on.
