Not Done Yet - Anthony W. Eichenlaub

You're never too old to change the future.

A resident of a nursing home discovers something strange when he orchestrates his escape heist. A mother must decide what to do when four copies of her son return from the Duplication War. An elderly villain writes one last letter to her superhero daughter. 

Fourteen stories of justice, beauty, and innovation that prove you don't need to be young to be ambitious. Too old to make a difference? 

Step aside, kid. We're Not Done Yet.
