Come on, how long has this forum been here and no one has mentioned him?

Sword of Shannara
Elfstones of Shanarra
Wishsong of Shannara

and that's only one series he has written, I'm currently reading Scions of Shannara, which is by far written the best of them all.

I agree that the Shannara books are very good books. I haven't read them all, but, I've polished off the original series, and the wishsong series. Good books.
