The year was 1891, and Ruritania was a small, seemingly insignificant Balkan country that was about to crown a new king. But a conspiracy headed by his own half brother resulted in the would-be king being kidnapped and held in Zenda Castle, an impregnable medieval fortress. While two factions secretly battled for control in Ruritania, an even more dangerous conspiracy was launched from the far future; one that was about to make a tiny Balkan country the focal point for plot to change the course of history. Her name was Sophia Falco, codename: Falcon, a veteran crosstime field agent of the TIA. She was smart, beautiful, and absolutely deadly. She was also a terrorist, a member of the infamous Timekeepers who had submitted to cybernetic conditioning that created a false persona under which she had enlisted in the Temporal Army Corps, and from there, joined Temporal Intelligence, at which point her true personality was triggered and the woman who had once been Col. Moses Forrester's lover was reborn as his most lethal enemy. And the weapon she was going to use against him was the son he had abandoned in another time. The elite commando team of Lucas Priest, Andre Cross and Finn Delaney have another historical adjustment mission to perform: save the rightful king of Ruritania and stop the Timekeepers before they can bring about a temporal disaster. And to do so, their commander, Moses Forrester, must journey back into the past with them to destroy the woman he once loved ... and murder his own son.
