The Martian

One of the best science fiction books I've read in years. Full of tension, and the “average Joe” tone of Mark really helps you connect with him.

I especially enjoyed the fact that the science involved was complex but understandable, it almost reminded me of Michael Chrichton in the way the realism contributed to the story rather than just being an info dump.

Overall, a fantastic book that any fans of realistic sci-fi must pick up!
