The one that immediatley came to mind is How to Live Safely in a Science Fictional Universe by Charles Yu. Here is the summary:
From a 5 Under 35 winner, comes a razor-sharp, hilarious, and touching story of a son searching for his father . . . through quantum space-time.
Every day in Minor Universe 31 people get into time machines and try to change the past. That’s where Charles Yu, time travel technician, steps in. He helps save people from themselves. Literally. When he’s not taking client calls, Yu visits his mother and searches for his father, who invented time travel and then vanished. The key to locating his father may be found in a book. It’s called How to Live Safely in a Science Fictional Universe, and somewhere inside it is information that will help him. It may even save his life.
I listened to this as a audio book and it was so strange that I quite half way through. It is one of my few DNF books. It just never seemed to have a theme or make sense.
