On the outside, Harriet "Harry" Lime is a typical American mom. But after years of packing all the lunches and picking up all the socks, she's become a bit...off on the inside. And after stumbling upon the offensive new statue at her daughter's school, she gets unusually angry and turns into a gigantic monster.

Now she'll have to figure out why that keeps happening-and why some mysterious uniformed men have begun lurking around town-all while keeping up with the grocery shopping, the carpool, and all those mother@#!&ing socks.

As soon as Harriet discovers that other local women are undergoing their own amazing transformations, she faces the sudden danger of being ripped away from everyone and everything she loves. Still, she's begun to wonder: How much of her old life-with its surplus of cleaning, cooking, and monthly cramping-does she want to hold on to, anyway?
