How to Live Safely in a Science Fictional Universe

In this fiercely original novel, Charles is a time-traveling repairman working in the off-kilter Minor Universe 31. He helps clients return to their biggest mistakes, which they incorrectly believe they can repair. But they can't-and that's bad news for Charles, who once accidentally ran into and shot his future self.
