It's the 1980s, and Ali and her best friend, Jessie, are on the cusp. In the simmering heat of summer, in their small coastal town, they are starting to chafe at the restrictions put on them by their teachers, their parents, and each other. Then Jessie suffers a devastating accident, and both their lives are forever changed. When Ali is an adult, with a young daughter herself, the news of Jessie's death unlocks the memories of that summer, forcing her to reckon with her own role in what happened to Jessie so many years ago. As this stunning debut moves back and forth in time, and Ali's secrets are forced into the light, Kate Ryan asks profound questions about responsibility and blame, and, ultimately, about love.
