This started out pretty good and then just went downhill. I'm giving it two stars mostly for the beginning and because I've adored Billy since the beginning of the series and really enjoyed Cody, especially in the first few chapters. About midway through though this book came dangerously close to me not finishing.
I'm starting to realize that I enjoy the books in this series when the focus is less about the shifters and the lore surrounding them and more about the MC's and their relationship. Whenever a new element is introduced into the lore like the shadows in previous books or what happens with Cody in this one (was NOT a fan of that at all) the train goes off the track and I find it a struggle to finish reading and am pretty unsatisfied and frustrated at the end. By contrast when the story is character, rather than plot driven, I tend to enjoy the books much, much more.
