Robert M Pirsig question.

So I've been re-reading Zen and the Art of Motorcycle Maintenance.  I know for sure that he has another book, Lila: An Inquiry into Morals. What I'm curious about is finding more of his work and others like him. Philosophy is better interwoven into a storyline as opposed to presented in a fact-of-the-matter non-fiction style. Seems to breathe life into a genre so beaten down by egos. Anyway, that's what I'm looking for if anyone can help. And if you haven't read Zen..., it's an instant classic. Pick it up.
