I loved this book, 5 stars. 
 I thought Crooked Kingdom was such a rich, detailed end to this duology. It made me laugh it made me gasp in shock and it made me despair to no end. The story is full of twists and turns, character development and plenty of bitter sweet moments characteristic for a gang of thieves and murderers you can't help but love. These characters and the story they told have a very special place in my heart. I grew to love each one of the characters, each distinct and each with their own difficulties. I thought Bardugo did an incredible job at providing detail to the book and developments to the characters. This is the first ending to a book I've nodded at and accepted. I thought this was a much better constructed and decided ending than the first Grisha series. It was the happiest ending conceivable in the barrel. 
 I can see myself re-reading and re-reading these books throughout the years. I don't particularly do that unless a book has really embedded itself within me and this duology definitely did. 
 Amazing book. Finish this duology if you haven't!
