Pulled forward in time by the Guild of a distant future, Assassin 101 is tasked with tracking down a rogue agent before he can return to his time. What he finds is a web of espionage bent on destruction and domination, and a family secret makes the Assassin doubt his own future. Sebastian Caine, a top level Apprentice, has duped the Guild into complacency. Sentenced to death for his crimes, he escapes into the past. Plans for a new life hinge on drastically changing the timeline. Rick Brewer has been a guinea pig for Guild scientists since his capture. Along with Assassin 97, he is sent to retrieve Caine, but his growing affection towards her becomes more pronounced as they bounce through the Renaissance in search of Caine. When Assassin 97 is captured and tortured, Brewer must make the ultimate sacrifice. To rescue Assassin 97, Brewer and Assassin 101 must violate Guild law and, with it, accept possible execution. Can Assassin 101 save his wife and his future, or will the Guild leave her to history?
