Cassie and Zoe Grossberg were once as close as sisters could be, but it’s been two decades since they’ve spoken. As a pop sensation in their early twenties, the sisters experienced the ultimate highs of celebrity, until a tragedy drove them apart.

Now Zoe is a suburban mom in New Jersey and Cassie is living alone, off the grid in Alaska. Zoe’s teenage daughter, Cherry, is chasing her own dreams of pop stardom. When Cherry is tapped to appear on a reality TV singing competition, she tries to reunite the women—and uncover the truth about what broke up the Griffin Sisters all those years ago.

Cassie and Zoe must face their past, confront old secrets, and try to forgive each other—and themselves.
