Last year at WYD Steve listened to a guy called John Pridmore talk and bought his book Gangland to Promised land.
I found it while I was cleaning out the storeroom and have started reading it.
John Pridmore is an ex London gangster turn Christian. (His own words). I have found his story very gripping and a wonderful testimony to the faithfulness of God. When I read stories like this, I know that nothing is impossible for God.
John also keeps a blog which can be found Here
