Sisters Red

This took me forever to finish, and I think it was because I wasn't really all that interested or invested in any of the characters. The Fenris is an interesting concept, but I wasn't clear on if it's every one of them that has to be a seventh son of a seventh son, or just the Potentials. In which case ... that seems like a lot of people to meet that requirement. I wanted this book to be a lot better than it was.
