How did this novel keep my attention the way it did? I don't know. In fact, I started this novel with some trepidation because I am not a math and science geek. This story is one tough problem solving task after another, and it's all over my head. And yet--Mark Watney, in his humor-spiked journal, kept me rapt. Perhaps it reminded me of Sherlock Holmes's deductions. Those are a bit easier to follow, but often contain a scientific element. I doubt Arthur Conan Doyle wrote as many deductions or solved as many problems in all his books combined as Andy Weir wrote for this one spare story!

I am so glad that I had not heard how this story ends before finishing it! Boy, was I on the edge of my seat....

Highly recommended!
