He is alone on Mars, everyone thinks he's dead and he has a limited amount of food. Well, that's not too bad right? He can just call Earth and everything will be okay. Great plan! If he had a way to contact Earth.
So yeah, he's gonna die.
The main thing that I liked about this book was the humor. Even though Mark is in a horrible situation, he kept making some really really funny jokes.
The main thing I did not like about this book was that some of the technical scientific parts were difficult to understand. Then again, the book was very accurate scientifically so I can't complain. Also, there is a large amount of cussing so read at your own discretion.
Overall I would give the book 5 out of 5 stars.
