#1 NEW YORK TIMES BESTSELLER! New York Times bestselling author of Anxious People returns with an unforgettably funny, deeply moving tale of four teenagers whose friendship creates a bond so powerful that it changes a complete stranger’s life twenty-five years later.

Most people think it’s just a depiction of the sea. But Louisa, an aspiring artist herself, knows otherwise, and she is determined to find out the story of these three enigmatic figures.
