The World That Couldn't Be

The World That Couldn't Be is a sci-fi story by Clifford D. Simak, published in 1958. Our hero Duncan is a farm owner on an alien planet, very alien, in fact, since no one, absolutely no living creature or plant has sex, for instance... But that's not the least of Duncan's troubles, as some alien life form is attacking his crops, the hunt is on. And what a hunt!
