This was probably one of my favorites so far (although I also loved the Pirate one). I loved this because it took place in a library and I love how the job of the Hairy Scary Librarian is to keep everyone away from the books and that Hiccup's mission starts out as trying to prove that he's as good a thief as any Viking to trying to convince all the Vikings that books are a good thing and they should be available to everyone! I loved that it was an adventure where the kids ignored the parents and Kamikazi, Hiccup, and Fishlegs decide to do something dangerous on their own and we get to meet Kamikazi's dragon, who is as tiny as she is. Overall, this was super fun and the perfect listen during my platelet donation! Highly recommended.
