Years ago, Nora Bridge walked out on her marriage and left her daughters behind. Now she is a famous talk show host. Her daughter Ruby is a struggling comedienne. The two haven’t spoken in more than a decade. Then a scandal from Nora’s past is exposed, and Ruby is offered a fortune to write a tell-all about her mother. Reluctantly, she returns to the family house on Summer Island, a home filled with frayed memories of joy and heartache. Confronting a past that includes a never-forgotten love, a sick best friend, and a mother who has harbored terrible family secrets, Ruby finally begins to understand the complex ties that bind a mother and daughter—and the healing that comes with forgiveness.
