When Chris Talberman's family moved to Wellfleet, Massachusetts, Chris left behind his boyfriend and friends. Six months later, Chris still feels alone.
When a pod of dolphins strand themselves on the cove outside Chris's house, his autistic younger sister, Cece, runs out to see them. A boy named Noah Silver helps catch Cece before she gets hurt. Noah is even more alone than Chris, and he's just as eager to find a friend.
Then everything goes downhill -- Chris's mother leaves, putting Chris's workaholic father in charge. With no one else to talk to, Chris turns to Noah, and their relationship deepens. But Noah has problems he isn't willing to share.
