This book was so good. I finished it a couple of days ago, but I wasn't sure what to say about it. I loved getting to see more about them. This added a lot to the world of Frozen and helped clear up some things. I really think this is one I want to reread. Some points of it seemed a bit slow, then there were some large time jumps that I wish there had been something that happened between them. But, overall, it was a really good book.
