Actually, they rolled like bowling balls.
Another posting on Simak. This, incidentally, was not to be his last look at the economic effects of alien invasion. The aliens of his The Visitors endanger markets by cheap production.
Raw Feed: They Walked Like Men, Clifford D. Simak, 1962.
A highly entertaining novel with a very unique alien invasion. (A gentle satire on slavish devotion to capitalism.) The story moved quickly. As usual, Simak does an excellent job of portraying his desperate, doubting protagonist. The usual Simak touches are there: the lovely rural settings, the gentle animal characters, and the strange aliens. As usual, science and technology are not crucial to the story. Simak barely gives an explanation for his bowling ball aliens’ mode of transportation. Here, his aliens are harder edged than usual. They actually kill people.
