Timmothy Zahn's Star Wars books are my favorite ever! I am honestly not much of a reader but I read that original series multiple times and own and have read the hardcovers all of his others. Zahn released an entire Thrawn novel a couple of months ago.

If you need a Thrwan fix, he was a MAIN character in the cartoon Star Wars Rebels on the Disney Channel. It is young Thrawn before Rogue one. It's awesome.

I have heard rumors of a stand alone movie or his inclusion in upcoming projects. Thrawn lives!!!
