Terry Brooks is my favorite Author. His SHannara Books, with a few exceptions, are amazing. I'll go ahead and list them in chronological order, (The only one that was relTeased outside of chronological order was The First King, which chronologically is the first, however was released after the original trilogy.)

The First King of Shannara

The Sword of Shannara.
The Elfstones
The Wishsong

The Scions
The Druid
The Elf Queen
The Talsimans

The Isle Witch
Antrax
The Morgwar

I forget the next three six books in the Shannara though, and I haven't read the last 3 yet.
