Douglas Gresham claims that Jack Lewis was the finest man and the best Christian he has ever known. Of course, Jack to Douglas is C. S. Lewis to the rest of the world. The informal address Gresham uses to refer to the great writer is indicative of the intimacy he shared with Lewis for a dozen years, living in England as Lewis's stepson.

Jack's Life is an affectionate account of days now long gone. It is a personal memoir of a man who touched many in the classroom, even more with his pen, and made a significant, lasting, and eternal impression on one young man. Douglas Gresham is uniquely qualified to offer such an extraordinary portrait.
