Wow!! What a ride! Mark Watney is the McGyver of Mars even down to the wise cracking gallows humor.
This is one of those books that I truly did not want to put down if for no other reason than so Watney would not be alone on Mars, as if somehow my reading his log actually did put me there with him. You can't help but cheer him on.
Oh and how many potatoes do you think you can eat before just looking at one makes you sick?
