Seventh grader Addie Bell can’t wait to grow up. Her parents won’t let her have her own phone, she doesn’t have any curves, and her best friend, Grace, isn’t at all interested in makeup or boys. Then, on the night of her twelfth birthday, Addie makes a wish on a magic jewelry box to be sixteen . . . and wakes up to find her entire life has been fast-forwarded four years! Suddenly she has everything she’s always wanted (including a driver’s license and a closet full of cool clothes)! But Addie soon discovers a lot more has changed than she expected - including her friendship with Grace. Can Addie turn back time and take back her wish . . . or has she lost the chance to experience what could have been the best years of her life?
