Little Dixie Reading Group - "Nash Falls" by David Baldacci

Nash is an intelligent man, tough but fair-minded. He has a wife and a daughter and a very high-level position at Sybaritic Investments, where his innate skills and dogged tenacity have carried him to the top of the pyramid in his business career. Despite never going on grand adventures, and always working too many hours, he has a happy and upscale life with his family.
However, following his estranged Vietnam-veteran father’s funeral, Nash is unexpectedly approached by the FBI in the middle of the night. They have an important request: become their inside man to expose an enterprise that is laundering large sums of money through Sybaritic. At the top of this illegal operation is Victoria Steers, an international criminal mastermind that the FBI has been trying to bring down for years.
Nash has little choice but to accept the FBI’s demands and try to bring Steers and her partners to justice. But when Steers discovers that Nash is working with the FBI, she turns the tables on him in a way he never could have contemplated. And that forces Nash to take the ultimate step both to survive and to take his revenge: He must become the exact opposite of who he has always been.
And even that may not be enough.
