I don't like space and I don't like survivor stories because they both stress me out, but I really enjoyed this book. Mark Watney is an engaging and funny character whose levity makes the life-threatening circumstances much more digestible. All of the science was well explained so that someone with absolutely no idea what they were talking about (I.e. me) could easily follow. 

I just really enjoyed the read. I was stressing for the character but it was well balanced with occasional triumphs and it kept me eagerly reading the next pages to see if Mark survived.
