Youll be safe here.Thats what the tour guide tells the Farmer-Bowens when they visit Plymouth Valley, a walled-off company town with clean air, pantries that never go empty, and blue-ribbon schools. On a very trial basis, the company offers to hire Linda Farmers husband, Russell, a numbers genius, and relocate her whole family to this bucolic paradise for the .0001 percent. Though Linda will have to sacrifice her medical career back home, the family jumps at the opportunity. Theyd be crazy not to take it. With the outside world falling apart, this might be the Farmer-Bowens last chance.

But fitting in takes work. The pampered locals distrust outsiders, snubbing Linda, Russell, and their teen twins. And the residents fervently adhere to a group of customs and beliefs called Hollow…but what exactly is Hollow?

Its Linda who brokers acceptance, by volunteering her medical skills to the most influential people in town through their pet charity, ActHollow. In the months afterward, everything seems fine. Sure, Russell starts hyperventilating through a paper bag in the middle of the night, and the kids have become secretive, but living in Plymouth Valley is worth sacrificing their familys closeness, isnt it? At least theyll survive. The trouble is, the locals never say what they think. They seem scared. And Hollows ominous culminating event, the Plymouth Valley Winter Festival, is coming.

Linda is warned by her husband and her powerful new friends to stop asking questions. But the more she learns, the more frightened she becomes. Should the Farmer-Bowens be fighting to stay, or fighting to get out?
