This book kept surprising me at every turn! I loved the characters and the snappy dialogue. It was a nice balance to the science jargon, which was easy to follow even to someone not from a STEM background.
I did enjoy The Martian a little more, writing style wise because the whole flashbacks with information that will be useful later was a bit clunky after a while. I think it sacrifices style for the sake of plot twists (of which there are plenty) which ultimately makes it 4 stars for me.
