This book contains two stories which despite the subtitle weren't exactly 'suppressed'. The first story, "Jesus on Mars", is an abridged version of the novel that was supposed to be printed in Isaac Asimov's Science Fiction Magazine. Due to editing problems and time constraints, the book came out before the story could be run. The second story, "Riverworld War", is a chapter that was cut from the Riverworld novel The Magic Labyrinth.
Philip José Farmer was an American author, principally known for his science fiction and fantasy novels and short stories. He was born in Terre Haute, Indiana, but spent much of his life in Peoria, Illinois.
Farmer is best known for his Riverworld series and the earlier World of Tiers series. He is noted for his use of sexual and religious themes in his work, his fascination for and reworking of the lore of legendary pulp heroes, and occasional tongue-in-cheek pseudonymous works written as if by fictional characters.
