How to Live Safely in a Science Fictional Universe

I wanted to like this book a lot more than I actually did. Neat premise, great writing, but dear Lord this book is so meta it's almost like there's nothing even there. There were a lot of intriguing plot devices that were just begging to be developed, but never were. In the end, the book was a moderately interesting character study about a boy's troubled relationship with his absent father. But in the end, I still really can't tell you much about time travel, and even less about what exactly happened at the end of the book.
