I read Zen And The Art Of Motorcycle Maintenance. Personally, I thought the book was quite good.
It's a very personal account of a man's journey while on a motorcycle trip with his son and two friends. It's a philosophical work, and yet those elements fit very well with the narrative.
If you've studied epistemology you might be more interested in this book. If you have any liking for Immanuel Kant, or David Hume, you might be especially interested in it.
