The setting is so weird. It really seems to be a Western or could have taken place in rural Australia as it was colonized. The science of Mars is all wrong of course; one character makes a living smuggling foods to Mars by rocket! The expenses would be so enormous that there's no way that would work, even with much faster travel. I think Dick just sets it on Mars to help it qualify as sci-fi for his readership. It wasn't bad at all but not what i was expecting. a 5 from me.
