He’s well known for writing a series called the Shannara series.  I read about 6 or so from that series so far.  Its good stuff, but I recently started another series by him called the Word & Void.  It’s modern day and is really well written.  I just looked it up on Wikipedia, and it says that this series is actually a prequel to the Shannara books.  That’s pretty interesting, but I haven’t read the book that is supposed to link them, it’s called The Genesis of Shannara.  I do actually have one of his later Shannara books on tape, K and I listened to it on a trip two years ago.  Pretty cool, I liked how he uses ruins of older civilizations as areas in his novels.  I guess that makes sense then that he then merges the current world to a post apocalyptic world with the later fantasy world.
