The measure of a good book is how much you want to read it (or in this case listen to the book – my copy came from Audible). I looked forward to the next installment to find out how our astronaut (Mark Watney) would survive being abandoned on Mars.
The book is quite technical and there is a lot of science in there. Most of it seems plausible and you should perhaps be more concerned about the number of times luck is on the side of Mark Watney than the accuracy of the science. The book does a fairly good job of exploring how it would feel to be left behind and to be the only living organism on the entire planet. There is plenty of Martian geography in the story and even reference to old Mars rovers that are not longer in use.
I would like to know what happens after the story – there were a number of plot lines that I felt would lead somewhere only to be abandoned at the end. The audio book is extremely well read and around 11 hours in length making it a good buy. I would recommend this book without hesitation.
