Best Mars Science Fiction Books

This is the crowd ranked list version of our 'Best Mars Science Fiction' list. All these books deal with mars in some significant way -- either as the setting of the story or as the major focus of the plot. The success of The Martian by Andy Weir and the subsequent Ridley Scott movie and the recent NASA findings about mars has made MARS all the rage again in pop culture, if indeed it ever went away at all.
