The Narnian: The Life and Imagination of C. S. Lewis
by Alan Jacobs, a review from The New Republic Online by Richard Jenkyns.
"Alan Jacobs observes in his book that C.S. Lewis seems not to have been a particularly likeable or interesting man before his conversion to Christianity in 1929. Lewis himself would probably have agreed. Looking back at that time, he recalled examining himself with a practical purpose for the first time and being appalled by what he found: 'a zoo of lusts, a bedlam of ambitions, a nursery of fears, a harem of fondled hatreds.' He was probably judging himself by standards that would condemn most of us even more severely, but certainly his conversion appears to have infused and changed every part of his life and action."
