Stepford Wives meets Big Little Lies in this twisty thriller that uncovers the untruths, petty grievances, and local school politics underneath a seemingly quaint small town.

Hamilton, Massachusetts is one of those suburban towns that appears untouched by the outside world where stay-at-home moms wear 2ct diamond studs to the playground, where a million-dollar property is “affordable,” and where the Parent Teacher Organization is a hotbed of controversy. Sure, some people struggle to make ends meet, but residents would say discussing such ugly matters is impolite. Hamilton has been like this forever, and everyone likes it that way. Or: almost everyone.

It's not that Anna Plummer doesn't like Hamilton, but she never thought she'd be married with two young kids, comfortable, complacent…and growing more bored by the minute. So, when she realizes her second grader won't be able to attend the "Ziti with Your Sweetie" school dance because she didn’t pay for a “Premium” membership, she snaps. She sends an email to the terrifying president of the PTO—and all hell breaks loose.

One year later, Anna is found dead in the frozen Ipswich River. Left to pick up the pieces, her husband, Denny, is shaken to his core. He's no expert, but he's seen enough Dateline to know that the police think he's the main suspect. If they aren't going to get justice for Anna, he will. Told through the alternating perspectives of Anna and Denny exactly one year apart, and with a shocking concluding twist, Valley of the Moms is a gripping look at the underpinnings of grief, the social structures of wealth, and the secrets people keep—even among friends and loved ones.
