The Green Hills of Earth is a collection of nine short stories and one science fiction novella by the renowned author of the genre, Robert Heinlein, who captivated readers for decades. The common element that unites all these stories is the exploration of traditional heroic themes in a future world. Here, Heinlein is more concerned with human behavior under strange and peculiar circumstances, rather than space technology or theoretical physics. The clash of free people with colonial slavery on Venus, the rise of a female engineer in a male-dominated space station, the decision of a young officer to sacrifice himself to keep Earth free are some of the themes included in the stories of the collection.
