EDIT: I gotta upgrade this to 5 stars because I've been thinking about how great this book was for days after I read it. 
 4.5 stars 
 I loved this book! I loved the characters and the story and the world it's set in (or should I say worlds because FRIGGIN PARALLEL WORLDS HOW GREAT IS THAT??) and the magic. Everything was just wonderful. There was little to basically no romance and I can't believe I'm alive to experience that. The characters weren't morally good or evil (except for the twins maybe); they all felt so realistic and so human. I liked the dark atmosphere and tbh I just really need A Gathering of Shadows right now!
