Many people have a book they read in their teens that changed their outlook. For some it's 1984. For me it was Greene's "The Power and the Glory". It, and the questions it raised, are still with me.

Monsignor Quixote I can also recommend. The others I read I have forgotten, except for Brighton Rock which I didn't like.

As a sibling commenter has said, if you have any form of religious background or have seen that world, his books speak with a depth I think it would be difficult to grasp without that.
