Growing up in hardscrabble Kentucky in the 1920s, with their mother dead and their stepfather an ever-present threat, Bertie Fischer and her older sister Mabel have no one but each other --- with perhaps a sweetheart for Bertie waiting in the wings. But on the day that Bertie receives her eighth-grade diploma, good intentions go terribly wrong. A choice made in desperate haste sets off a chain of misunderstandings that will divide the sisters and reverberate through three generations of women.

What happens when nothing turns out as you planned? From the Depression through World War II and Vietnam, and smaller events both tragic and joyful, Bertie and Mabel forge unexpected identities that are shaped by unspeakable secrets. As the sisters have daughters and granddaughters of their own, they discover that both love and betrayal are even more complicated than they seem.
