I enjoyed it. It was similar to The Martian, in that someone has to science the shit out of a life-threatening situation, but everything else is very different and the stakes are so much higher. So you do indeed get a new book despite the broad similarities. The characters were fun and I can see how they will translate onto the big screen with the upcoming movie adaptation. Recommended if you enjoyed The Martian or if you enjoy a lot of science facts and their application or if you want to know beforehand what happens so you can focus more on Ryan Gosling.
