The Perfect Assassin by James Patterson in Paperback

At this particular institution, survival is the first lesson. Dr. Brandt Savage's plans for a year-long break from his position at the University of Chicago take a drastic turn when he becomes the only student at a school run by his captor. Despite her relentless methods, Savage is determined to learn as much as possible - even though he has no idea why he was chosen or what his captor expects from him. As he delves deeper into her background, Savage discovers their lives are intertwined and together they must make a promise: to do right by all and wrong by no one.  Praise for James Patterson 'The master storyteller of our times' Hillary Rodham Clinton 'James Patterson is the gold standard by which all others are judged.'
