I don't even remember pre-ordering this book. It just showed up in my Kindle app this morning. So I decided to read the first chapter before starting work. Four hours later, I can finally put the book down since I'm done. "The Martian" was a great story. "Artemis" was a great story. This one is better than either of those. If you like science fiction with actual science, this is for you. If you like stories with interesting, well developed characters, this also has that. If you want excitement and a thrilling plot, here you go. If you want romance and sex, well, there you're completely out of luck. But if that was the kind of book you wanted I doubt you'd be reading this review anyway. Speaking of, why *are* you still reading this review? Go read the book!! It's way better than this.
