My image of Mars was seriously influenced by this book that I read as a small boy of 12 years, or 13:
Robots!
Many robots!
Laser beams! Jungles of meat-eating tentacle swinging plants! Ghost towns full of computers! One man all alone! Pure Magic for a boy of that age. I read it in one rush (like most books at that time), and could not sleep for two nights, for i was so excited and my imagination ran amok.
Ray Bradbury writing about a boy who has read this book - that would be something!
