|New English Library paperback, 1978. Cover by Joe Petagno.|
Rear cover synopsis:
"Three astronauts had returned safely from the Mars landing. Two were dead and Steve West was on the run. On the run from the quarantine hospital which had been treating him ... from the authorities who had to conceal his escape at all costs ... from his friend Ted Nelson ... and from the dreadful organism which had taken possession of his flesh, turning him into a fiendish nightmare but leaving his mind intact to cringe from the murderous horror he had become."
I feel the need to point out that the only reason I bought this (tie-in) book was because I remember seeing the film in all its awfulness on Mystery Science Theater 3000. As a bonus, the eye-catching cover painting is by Joe Petagno.
