The Enemy Within

Erica Shepherd was one of the CIA's most brilliant operatives until she became one of the greatest traitors in American history, serving a life sentence in a Supermax prison. Now, to save her daughter, she must team up with FBI agent Will Keaton -- a man whose life she destroyed -- to track down a fiercely dangerous, elusive criminal and his legion of spies. While working with Shepherd goes against every fiber of his being, Keaton knows that sometimes to catch a spy, you must trust one.
