Oliver Grant is an American intelligence officer, a hero of the Vietnam War. But when the Mafia kidnaps his sister, his life is turned upside down and he agrees to complete a dangerous assignment for the powerful mob boss Dimitri Stavrou in order to gain her freedom: Grant must save Stavrou's son from a secret cliff-top prison in Libya.

To accomplish this mission, he must scale the rocky crag and somehow get Stavrou's son out alive. His sister's life--and his own--hang in the balance in a nerve-racking tale of action and suspense from the author Tom Clancy called "the master," with more than a quarter of a billion copies of his thrillers sold around the world.
