4.5 stars, really. Would have been 5, but I'm trying to be more selective with my perfect scores.
Anywho, this book was incredible on several counts. First and foremost is the science. Never before have I read hard science fiction so accessible, and the humor went along way toward that, but honestly the scientific applications just felt real throughout. The problems were consistently variable and escalated in intensity, and the solutions were always equal parts genius and digestible simplicity. Does that make any sense? If Andy Weir were writing this review, it probably would.
