Coming of age isn't just for kids. In a small town in upstate New York, Astrid Strick - mother to three grown-up children - is keeping the kind of secret that once upon a time would have rocked the very foundations of her careful, suburban life. But thankfully the world is changing and, with it, her family. The time has come for Astrid to confront past mistakes and present truths. But 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 daughter. And her 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, Cecelia, and her new friend really understand the courage it takes to tell the truth to the people you love the most. Emma Straub's unique alchemy of wisdom, humor, and insight come together in this deeply satisfying story about how to survive inside a family, no matter what follows us into adulthood. Whether you are the eldest, the youngest, the middle, the only - this is a book for the adult hiding in you.
