Someone or something left the module for him to find...

When Carl Shelton was fifteen years old, he discovered an object in a forest that would change the rest of his life. Someone or something left the module for him to find. He spent the next seventeen years experimenting with his discovery, which led to his ability to travel in time, both into the past and into the future.

The module gave him fabulous wealth, a firsthand glimpse of historical events, and revealed to him humanity's dark future. While traveling in time provided him with adventure, a new family, and riches, it was not without near-death experiences and heartaches. Who or what was the entity that endowed him with the most important finding since the discovery of electricity? All he knows is that someone is watching him during every trip he makes.
