After returning Abraham Lincoln to his seat in Ford's Theater milliseconds before Booth fires the pistol, Will Burleson's Portal team flees a hit team sent by the President and arrives 5 years late at a new secret location.
The team struggles around the clock to rescue stranded astronauts it placed on Sol's planets and moons with heartbreaking results, and they mount a rescue for two friends marooned in 1865 where over 5 years have now passed.
The team's Portal slips into 1804 in an attempt to make scholarly observation of the Lewis and Clark Discovery Expedition and they get more than they bargained for. Their crossing of the 1808 Virgin West is tumultuous and magnificent. Their parallel expedition rewrites the known history of the pre-Louisiana Purchase Indians.
