Sleepers of Mars [ssc]

[Stories are sometimes listed as being written by either John Beynon Harris or John Beynon.]
Coronet Books recently published STOWAWAY TO MARS, one of John Wyndham’s most famous stories. The title story of this collection, though it can be read as a separate entity, pursues the ideas thrown up by the original novel, drawing them to some fascinating conclusions.
Of course, we are now well used to the idea of Man On The Moon, we have become blasé as to the possibilities of inter-planetary travel. But imagine two expeditions to Mars, one British, the other Russian, both in the process of discovering a mechanical race, invented and produced by the Martians as they believe their specie to be dying.
The other four novellas in this collection give further evidence of John Wyndham’s genius at invention, characterisation and sense of movement.
Contains:
SLEEPERS OF MARS : Disturbed from the sleep of centuries, they found they had been cheated of their future. Fertile plains were now endless barren desert .  .  .

INVISIBLE MONSTER : The crashed spaceship held a hidden horror - it was man-eating and it was multiplying!
