"Hey there." declared Mark Watney to his first potato plant. This was an interesting book. I enjoyed reading it, but at the same time I was pulled onto Mars and into Mark's world. He had a lot of food-the rest of his crew aborted misson and left him there, supposedly dead. But no! He was alive, and (partially) well. (Except for the fact that a satellite slammed into him and stabbed him, but that's unimportant.) With the potatoes in his food stash, he decided to grow some. And maybe set himself on fire once. Maybe. Then, his potatoes died. Nobody likes cold temperatures on Mars. Then, Rich Purnell decides to try to help save him. NASA declines. But the rest of the Ares III crew (those rebels!) use Rich's maneuver. And Mark is saved. The rest you know.
