How to Live Safely in a Science Fictional Universe

I have to say this book was a quick read for me. That being said I gave it three stars, because it was an average Sci-fi novel. I enjoyed the content, but thought it was missing something. I am not sure what that is, but in the end it felt unfinished and incomplete. Although I hate to admit this, I was a little confused at the end and had to re-read it a couple of times to make sure it was truly the ending. I do recommend this book, but with the understanding that it is not the best that I have read. I do look forward to more from Yu.
