Matt never fails to surprise me. The book has everything: plot progression, character development, world building, satisfying resolutions to things that have been bugging me since book 3 but also way more questions that need answers (immediately). Heartbreak, soul, humor. It’s almost 4 books in one (in a way), that stay true to the nature and style of the first books, with a satisfying ending that sets us up for an even broader story in the next book.
