This is entertainment fiction, specifically science fiction. As I read less and less genre fiction, it takes a lot for me to stick with such books. I tend to gravitate towards literary fiction because I love the unsaid contract between author and reader that states: if I (the author) accomplish this properly, you (the reader) will be wholly invested in my character(s).
Now, having previously read a Sawyer book which I did enjoy tremendously for its ideas (back when I wasn't so picky), namely The Terminal Experiment, I decided to give this book a try since it's been on my shelf for a while. I've recently downsized and reorganized my library, getting rid of some 200 books, mostly genre based or non-fiction that I don't intend to reference anymore. So, I needed to decide whether this stays or goes.
