I bought this book because I'd heard it's good. It didn't disappoint! It's a great story with lots of tension about what's going to happen. One of the things I really liked is how the author explains some of the science behind the science-fiction stuff / technology (such as the ships). What I liked less were the scenes with sex in them, but that's probably just me. It's not that descriptive or anything, one of the characters has intercourse with several people over the course of the book, and this is not something that I agree with, thus I couldn't feel for this character as much as for some of the other characters in the book. Overall though it's a great book, quite well written. It's an epic science-fiction story (this is part one of the trilogy, the story does not end in part one).
