Astrid Strick -- mother to three grown-up children -- has been keeping a secret. Just as she is finally warming up to share her secret with her family, a forgotten memory from her younger parenting days is jostled loose, and it's not a good one. The secrets are multiplying, it seems, and so are her mistakes. Suddenly, Astrid realizes, she may not have been quite the parent she always thought she was. But to what consequence? And is it too late to set things right? Astrid's youngest son, Nicky, is drifting and unfocused, making parenting mistakes of his own. Her single daughter, Porter, is pregnant yet struggling to give up her own adolescence in time to greet a baby. And Astrid's eldest, Elliot, seems to measure his adult life according to standards no one else shares. But who gets to decide, so many years later, which were the mistakes that mattered? It might be that only Astrid's thirteen-year-old granddaughter and her new friend really understand the courage it takes to tell the truth to the people you love the most.
