13 Little Blue Envelopes is about a girl named Ginny who explores Europe with only letters from her wacky, dead aunt. Each letter contains a task for Ginny to do and after she completes the task she can open the next envelope. Sounds fun right? Well Ginny is by herself and she starts to get lonely as the place she explores get more and more less familiar. While I was reading this I found myself staying up well past my bed time reading this book, eager to find out where the letters would lead Ginny next.
