read the Empty Mirror by Jan Willem van de Weteringe.
Dutch dude who not long after WW2 went to become a ZEN monk in Japan.
He tells the story in a very good, humorist way, you'll love it either way.
It's not so much a book about strict budhism or Zen or anything.. But it covers some good ground
I got that suggestion from my Kendo sensei, It puts things in perspective in more ways then one.
