One summer that shaped her future.

There's something about summertime that feels momentous when you're at the edge of thirteen, and Madison Harlow wants to make the most of her last summer as a child.

Set in the idyllic seaside town of Carmel-by-the-Sea, the Harlow family's summer vacation is as fun as a family vacation can be. But with a changing body and bruised emotions, Madison is finding this break away from childhood more painful than she could ever have imagined.

Walking on eggshells around her mother, who always prefers her younger sister, Madison must come to terms with what it means to be an adult and the choices she must make to be treated like one. Scorching sunshine, delectable sandy beaches, and an encounter with a fearless boy with a knack for mayhem, this summer will lay the groundwork that will shape the rest of her life.

To be what others expect of you or to be who you want to be - that is the question Madison Harlow must answer.
