Special operations officer Jason Thanou of the Temporal Regulatory Authority must once again plunge into Earth's blood-drenched past to combat the plots of the Transhumanist underground to subvert that past and create a secret history leading up to the fulfillment of their mad dream of transforming humanity into a race of gods and monsters.



The transhumanists are attempting to use the chaos of the American Civil War to escape the Observer Effect: the immutable law that recorded history cannot be changed. If any should attempt it, time has a way of dealing with those transgressors in a very brutal, very final fashion. Now it is the last days of the Confederacy, and the Fall of Richmond looms. In the Shenandoah Valley, in the region later known as Mosby's Confederacy, insurgency brews, and the time travelers must join the raiders to prevent a transhumanist trap from dooming the mission from the start.



Yet human freedom is ultimately on the line in both the past and the future, and the leader of a secret slave underground fighting for liberty possesses an incredible secret that may change Jason's fate—and that of the future itself—forever.
