A group of young girls descend on Camp Forevermore, a sleepaway camp in the Pacific Northwest. Their days are filled with swimming lessons, friendship bracelets, and camp songs by the fire. On an overnight kayaking trip to a nearby island, they find themselves stranded, with no adults to help them survive or guide them home. Five girls-- Nita, Kayla, Isabel, Dina, and Siobhan-- survive the trip, and as the following years bring successes and failures, loving relationships and heartbreaks, we see the many ways a tragedy can alter the lives it touches.
