I really liked the other books in this series when I read them several years ago. I was crazy over Cole even though he wasn't the main character, and I had no idea that he had his own book. I just happened to stumbled upon it. Even though it is part of The Wolves of Mercy Falls series, it has a very different feel from the others. They were more YA fantasy romance, and Sinner is more of a NA rockstar romance. The others really centered around the werewolves, but this is mostly about Cole's life separate from the pack. It doesn't have the suck you in ups and downs of the other books. It's more of a lighter read. I did like it, but I missed the feelings I had from the others.
