Book 7 is my favorite. I actually liked book 3.Books 3 and 6 were my least favorite. Books 5 and 7 were my favorites.
I found the train station stuff in book 3 to be unnecessarily convoluted. I believe there was even a disclaimer at the start of the book that was like, "it's going to be really convoluted... just roll with it and realize that by the end will make enough sense"
