A new Sisterhood for a new summer, a time to grow, to plant the seeds of friendship and harvest for the future. Polly has an idea for a more glamorous life, but it's going to take a few changes. Jo's hanging with her new, older friends at her family's beach house but she didn't count on a brief fling or feeling embarrassed by her middle-school friends. Academic Ama lands a summer scholarship on a wilderness trip full of flirty teenagers, blisters, impossible hiking trails and a lack of hair products. For all three girls summer is a time to grow.
