All Flesh Is Grass
A mysterious invisible barrier suddenly encloses a small, out-of-the-way American township. It's been put there by a galactic intelligence intent on imposing harmony and co-operation on the different peoples of the universe.
But to the inhabitants of the town the barrier means fear of the unknown, a stark, unreasoning terror of the alien civilization which has taken control of their lives.
