We lost one of science fiction’s most prolific and inventive authors this week. 

Farmer won the Hugo, the genre’s most coveted award, three times.

His best work was a series of books set on an artificial planet which consisted of a single, curving, million-mile-long river, on whose banks every human being who had ever lived was mysteriously reincarnated. 

Farmer was a pioneer in exploring both sex and religion in science fiction.  He was almost 90 years old. We will miss him.
