Such a Fun Age by Kiley Reid

A Reese's Book Club pick and instant New York Times bestseller. Alix Chamberlain is a woman who gets what she wants and has made a living showing other women how to do the same. So she is shocked when her babysitter, Emira Tucker, is confronted while watching the Chamberlains' toddler one night at their local high-end supermarket. The store's security guard, seeing a young Black woman out late with a white child, accuses Emira of kidnapping two-year-old Briar. A small crowd gathers, a bystander films everything, and Emira is furious and humiliated.

Alix resolves to make things right. But Emira herself is aimless, broke, and wary of Alix's desire to help. When the video of Emira unearths someone from Alix's past, both women find themselves on a crash course that will upend everything they think they know about themselves, and each other.
