I just finished reading 13 Little Blue Envelopes by Maureen Johnson. Here is what I thought of it. I really enjoyed this book. I love how the book is not done in chapters but it is broken down into the number of letters. Example letter 1.2.3 all the way to 13. I would recommend it. You get to go on an unusal adventure when you read this book but I guess when you read you go on all kind of adventures.
