His short story 'The Thing in the Stone' is also quite interesting. It combines elements of mystery and science fiction in a really engaging way. The story takes you on a journey through an alien landscape within a stone, making you question what's real and what's not. There are complex themes about perception and existence in it.
Another good one is 'The Cachalot'. It delves into a different kind of science - fiction world, exploring the relationship between humans and a very different kind of intelligent being. The story is rich in detail, from the description of the alien species to the unique environment they inhabit.
