This book was AMAZINGGGGG!!! I loved how powerful Katsa felt, but that she still allowed herself to be vulnerable at times, and really realized her own strength and abilities with time. The romance was great, but didn't overpower the story or make Katsa make dumb decisions. But Po, oh Po, I loved him from the very beginning. The mystery was awesome. When everything comes together, you're like "Oh my gosh, this book is the s***." I loved it from beginning to end, and best of all, no cliffhanger, although I am very interested in reading more from this author. This is the kind of book you're mad at yourself for not reading sooner, when you finish it.
