Do you ever really know the people you love?

For the Gold sisters and Silver brothers, life has been idyllic, growing up in side-by-side waterfront mansions in a town where doors are never locked and the police do little more than issue speeding tickets. The Golds and Silvers have known each other their entire lives, as neighbors, as friends, as family.

But one carefree summer takes a dark turn when a beach party ends in tragedy and their perfect world cracks wide open. Suddenly, the bonds that tie these families together are strained by suspicion and fear. Painful secrets surface, revealing the fragile truths they've all been hiding.

Lucy, the oldest Gold girl, harbors a crushing secret from her boyfriend, one of the Silver boys. Millie, the middle sister, quietly yearns for the one person she can't have. And the youngest, Frankie, uncovers something that could blow their island apart.

From New York Times bestselling author Jessica Goodman, comes a gripping novel about the lies friends tell, the façade siblings build, and how one summer tests—and breaks—the bonds of family.
