Query: don't waste your money or your time

I read prose for the enjoyment of the reading. I read every word and I don't skip to the end to find out how the story comes out. This book was a singular exception. Boring, at least 3 times too long, more concerned with a pointless love triangle than with Mars. I only finished it by skimming, stopping every four or five pages to read the few paragraphs necessary to follow what little plot there was. Unless you're into existential philosopy, the ending is a total joke. The descriptions of Mars surface geology are interesting, but that's about it. Stephen King could probably turned this into a good short story.
