The only thing keeping this book from a full 5 stars is the fact that I'm still upset about a choice Leigh Bardugo had made in writing the end of the book. I won't spoil anything, but I will say, I have never cried harder over anything. This book opens where we left off with Wylan wearing Kuwei Yul-Bo's face, and our gang must rescue Inej, get revenge, and defeat the bad guys. But that doesn't even begin to sum up all of the action, adventure, and craziness that this novel entails. And as well as being dark and compelling, the characters and relationships we love become even more fascinating and developed. Kaz and Inej, Jesper and Wylan, and Matthias and Nina have come quite far with each other, and draw me in more and more as time goes on. This found family has been and always will be my favorite group from any novel. The ending was devastating, but it was absolutely amazing. It was the kind of ending a story like this deserves -- the kind that leaves you wanting more, but knowing that it finished in exactly the right place.
