Something very strange is happening in Vermont. It's not The Game of Sunken Places - Brian and Gregory have been through that before, and there's not supposed to be another Game until they say there's a Game. But still . . . when they go to visit a relative in the Vermont woods, they find many things are . . . off. Like, people aren't where they're supposed to be. And houses are everywhere. In fact, the houses seem to be taking over.
