Snarky and fun. It is a great book, it had it's faults...but still a great book. Weir chose to be much more Science Fiction over Science Probable like The Martian, but still a good set of science lingo and details. I had a hard time maintaining empathy with Jazz throughout the book, maybe that was part of the story...but I don't think so. She does set herself as someone that deserves her plight, but you stick with her. Definitely worth the read.
