How to Live Safely in a Science Fictional Universe

How to Live Safely in a Science Fictional Universe (2010) by Charles Yu. Charles Yu is a character in his own book, which is a book within a book, and in which he becomes stuck in a time-travel loop that has him shooting his future self after he gets out of his time machine. Do you find that at all confusing? Because I found it dense as hell. This book was an easy read, but I had to skim portions of it because they just did not make sense to me, encrusted as they were with pseudo-scientific, made-up jargon. Unless you're a supreme science geek, or a science-fiction geek, I would not recommend this book. Otherwise, you might really enjoy it. Grade: B
