An old pair of faded blue jeans , probably the last thing to come to mind when thinking of a bonding farce to keep four close friend together on their separate ways for the summer. Well, that's what happens when Carmen leaves for North Carolina to see her dad, Bridget goes to Baja California for soccer camp, Lena goes to Greece, and Tibby stays at home working on a documentary. So, throughout the summer they send the pants to one another with a description on something special that happened to them while wearing the pants. This book is great for those who love "best friends forever" books. I personally did not like the book but I do think it is a well written story. Read the book to find out if the pants help the sisterhood!
