The books are great if you are into "weird" sci-fi books :) I enjoyed reading all the books (If I recall correctly the trillogy had four books :))
Check out your local library, I am sure they have the books or maybe they can order them from another library.
I just did a quick search on Amazon.com and I found many hits both book and audio.
