Andrea Hendricks is an agent with the KGB.
This three-book series is about the short career of a Soviet infiltrator, a beautiful woman trained for years to think and act like an American so there is no chance of slip-ups when sent into the field. What no one could predict, however, is the effect that falling in love with the enemy can have on the agent's actions.
At a very young age, the girl who would become Andrea Hendricks was placed in the training facility outside Moscow known as Little America. There she was given constant practice living and thinking like an American, all the while being indoctrinated in Soviet thought. She had very few friends, so no real ties, and nothing that would make her pine for the Motherland. The system worked too well, though. When she went on station and met a man with whom she fell in love, she had nothing to hold her to her old life.
Except the fellow agents who soon wanted her dead.
Playing a major co-starring role in the series is Greg Elliot, a brilliant computer programmer who had made a lot of money in a Silicon Valley startup that he had helped become a darling of Wall Street. Cashing out much of his stock, he purchased a beautiful home in the Valley and seemed set for life until that company went bankrupt and Elliot went back to work.
Elliot, still a fairly young man and considered good looking, is the target of Hendricks in the first adventure and the man she fell so deeply for. The feelings were reciprocated by this genius who was marked by the KGB as the leader in new cipher technologies that could make the American communication impenetrable.
Get to Elliot to get to the code was Hendricks' orders. The trouble was they got to each other and both will pay the price as the KGB and the CIA each want to use them in their constant fight.
