Gifted a belt that allows him to time travel, a man reorders the universe to suit himself.
I checked out The Man Who Folded Himself because the Kindle version is only $2.99. I am really glad that I did, because I was totally riveted by this book. The book really exploits the time travel premise to a brain-busting extent, but also maintains a solid emotional core. David Gerrold holds nothing back, and the result is just fascinating.
