Seventeen-year-old Kid doesn't know where her parents are. They left her with her grandmother Lolly months ago, promising to return soon. Now Lolly is dead and Kid is stranded ten miles off the New Hampshire coast on tiny Swan Island. With no other relatives to turn to, Kid works for a neighbor airbrushing the past - digitally retouching photos and movies - for money to survive. But Kid's island home is populated by a group of elderly separatists who fled the youth-obsessed mainland. They call themselves the Swans. Kid calls them the Wrinklies. Her presence unnerves them, and they want her gone. But Kid isn't the only problem threatening the insular community.
