Every summer, Libby Wilson heads to Cradle Bay, Massachusetts with her parents and her best friend Marina. Every summer, Libby and Marina spend their vacation with the Porter brothers, Levi and Noah, from down the beach. Every summer they swim in the ocean, lay in the sand, ride their bikes to the pier for ice cream and roast marshmallows over blazing bonfires. Every summer is the same. Until this year. Libby and Marina have always been just friends with the Porter brothers. But this year, Marina and Levi are hitting it off in a different way than usual. This year, Noah is looking at Libby in a way he never has before. This year, Libby's parents are acting differently, like maybe they're hiding something. This year, everything is different.
