First off, I would like to say that I'm 15 and it is my favorite book so far.This book, along with Maureen's other book The Key to the Golden Firebird, is amazing! I was definitely interested as I was reading The Key to the Golden Firebird because it was a very, very emotional book. When I got to the book store and saw 13 Little Blue Envelopes, I was so so sooo excited to read it because of the author. Reading the back of the cover made me fall in love with the book even more because it involved traveling to EUROPE! That is probably my biggest wish-to travel all over Europe alone. This book became my favorite extremely quickly. I recommended this book to my 16 year old sister, but she said it was the most boring book she has ever read; there must be something wrong in the head...
