Edward has one chance to save a man he forgot he ever loved. All he has to do is destroy the world. The disastrous events of the Zenith mission behind them, Marty and Edward lead very different lives at either end of time. Martin has been tapped to lead an elite military operation designed to curtail and ultimately eliminate the threat of time travelers. But Henry Bradford has other ideas, and seeks to entice him into taking up the role of captain of the rechristened starship Azimuth. Almost a quarter century in the future, Edward lives a life of wealth and influence as the adopted son of Starfire's CEO, Trevor Sutton. But the mystery of his birth father's murder still weighs heavily on his mind, eclipsed only by the baffling appearance of Martin's dogtags around his neck. The distance he will go for answers will determine the ultimate course of human history, as he is pitted head to head once more against the destructive agenda of the time traveler he knows only as Gifford.
