From the author of Good Neighbours, described by Gillian Flynn as 'wildly entertaining'. An absorbing and astute satirical thriller about a family's odyssey into an exclusive enclave for the wealthy that might not be as ideal as it seems.

As the outside world literally falls apart, Linda and Russell Farmer-Bowen and their teenage twins are offered the chance to relocate to Plymouth Valley, a walled-off company town with clean air, pantries that never go empty, and blue-ribbon schools. The family jumps at the opportunity. They'd be crazy not to take it. This might be their last chance at survival.

But fitting in takes work. And the strange residents fervently adhere to a group of customs and beliefs called Hollow... but what exactly is Hollow? Finally, thanks to Linda's medical skills they begin to find acceptance, and everything seems fine. Sure, Russell starts hyperventilating through a paper bag in the middle of the night, and the kids have drifted like bridgeless islands, but at least they'll survive. But something isn't right. The more Linda learns, the more frightened she becomes. Should the Farmer-Bowens be fighting to stay, or fighting to get out?
