This is a sequel to 13 Little Blue Envelopes. But they both are fantastic!!! They are really interesting, exciting and fun!! Its about a girl who receives 13 letters from her aunt who has just passed away. Each letter has instructions to do something. The first letter sends her over seas, alone. Alone as in no phone no computer nothing! Each letter takes her on a great adventure that changes her life. At the end (spoiler) the last letter is stolen along with the rest of her stuff, before she gets a chance to open it. This book is the adventure of that letter.
Great books! LOVE them!!
