We skipped Book 3 because our branch library doesn't have it and because I read online it doesn't impact the continuity. Our kids love these stories and I like to read them. Maybe it's because I picked them out of the library to start with, so every time I read them it's like I get to say, "I'm a good book-picker-outer." I think the first two books were a little better, though. The ironic endings of these stories seem less satisfying than those of the previous stories, which felt more thought-out.
