How to Live Safely in a Science Fictional Universe
Pantheon Books, 2010
“When it happens, this is what happens: I shoot myself.
Not, you know, my self self. I shoot my future self. He steps out of a time machine, introduces himself as Charles Yu. What am I supposed to do? I kill him. I kill my own future.”
Time-travel technician Charles Yu has found himself stuck in the very kind of predicament he is employed to help others extricate themselves from: Yu is trapped in a time loop, initiated by shooting his own future self. With only TAMMY, his time machine’s overly apologetic operation system, and Ed, his “nonexistent but ontologically valid dog,” for company, Yu sets out to unravel the mystery of his present difficulties, the key to which seems to be a book he received from his future self.
