This book is written by Ann Brashares. This book is really good. This book is about four friends who are going to be going to different places for the summer for the first time and they get a pair of jeans that they send to each other. This book was different than I thought it would be. It is easy to picture what is going on in the book. Once you start reading it you don't want to stop. I think the age groups that would like this book are 12-16. You can't really imagine what is going to happen in the next book.
