Such a fun age by Kiley Reid

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 young black babysitter, Emira Tucker, is accused by a security guard of kidnapping the Chamberlains' toddler at the supermarket one night. A small crowd gathers, a bystander films everything, and Emira is furious and humiliated. Alix resolves to make it 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.
