Four families traveling in trailers and spending the night at a campsite wake up in another world. There is no sun—nothing but grass stretching to the horizon. The soil absorbs blood instantly, and everything planted in the ground begins to grow right away. Each of the heroes ended up here not by chance, but no one can admit it even to themselves until something appears on the horizon—something strange. Something terrifying. And it’s moving toward the people trapped in this place. The unwilling travelers don’t yet know that the new world is full of surprises; that a real monster is lurking right nearby; and that even the worst nightmares and deepest fears are not the end of what awaits them here.
