"The Long Afternoon of Earth" is about life on Earth an unimaginably long time from now. Man's civilization is long gone, and humans are a minor species struggling for survival in an ecology dominated by highly evolved plants. Some of the science in this novel has been superceded or is simply wrong, but that does not change the fact that this is an imaginative and enjoyable story about the ultimate fate of mankind and the Earth itself. In this novel life is within a foreseeable distance of its end as the sun is becoming unstable. The world is incredibly dangerous for humans who can do little more than survive, if that.
