I've read about 15 of the books. I think my favorites were the Timothy Zahn trilogy, with Admiral Thrawn.
I was hooked on these for coupla years, but haven't been able to get back into them nowadays.
Timothy Zahn definetly wrote the best ones out of all of them, Thrawn was such a complex bad guy. Supposedly there are a few Thrawn books that I have never been able to find though.
I loved these ones. Thrawn was so cool, and those little ninja death claw creatures (i forgot their name, but they were SICK!), and the ysalimari...whew! that was good reading!
Oh, I forgot to mention Joruus C'Boath!
