An accomplished photographer and the devoted mom of an adorable little boy, Allie Ross has just moved to an upscale DC suburb, the kind of place where parenting feels like a competitive sport. Allie's desperate to make a good first impression. Then she's framed for murder.

It all starts at a neighborhood party when a local dad corners Allie and calls her by an old, forgotten nickname from her dark past. The next day, he is found dead.

Soon, the police are knocking at her door, grilling her about a supposed Tinder relationship with the man, and pulling up texts between them. She learns quickly that she's been hacked and someone is impersonating her online. Her reputation-socially and professionally-is at stake; even her husband starts to doubt her. As the killer closes in, Allie must reach back into a past she vowed to forget in order to learn the shocking truth of who is destroying her life.
