Always when writing about time travel, we need to remember potential paradoxes. Yet what if the protagonist's purpose is to create one? Or if the people sending the traveler back knows they'll be birthing a paradox that if successful will alter all history after the event?

Might even eliminate them. A paradox within a paradox. If you eliminate the creator of time travel, would she have created it?

I love time travel. It allows me to delve into the history of a time past and if researched correctly, allows me to better understand the people who lived then. Since I'm creating charactors from both the past and distant future, I try to run underlining contrasts based on what existed in each time.

Six hundred years from now, assuming humanity doesn't destroy itself first, no one will know what a handheld digital device was. It's likely they won't know social media existed, at least in the form we use it now.

There's more but later.
