Doug Cameron and Erin O’Neill are on the run from the arrows and spears of barbarian tribes, as well as the advanced aircraft and high-tech weapons of an evil empire that rules over the future…several thousand years from now. Using creativity, and whatever technology is available to them, Erin and Doug, and their friends and family, take on the full resources of a global empire. An empire that wants to dominate the world and seeks revenge upon the enemies they have identified across time and space. The adventures of the many versions of Doug and Erin, and their family and friends, make for an incredible story as everyone tries to survive constant threats and the challenges of daily life in multiple time periods from the year 1790 to the year 7245. And they experience so many strange events that they will even begin to question the nature of reality and their own sanity.
