I like "Vector Prime" and "Dark Tide I: Onslaught" out of the NJO series. (The only ones I've read out of the series so far)
"Courtship for Princess Leia" was good to.
"Ghost of Tatooine" isn't that bad (No Jedi, just Han, Leia, Chewie and 3po)
The Jedi Academy trilogy was cool
"Shatterpoint" is good for the Mace Windu fans
The ending to the thrawn trilogy was kind of a let down for me...Luke didn't kill any of the Dark Jedi. He just fought them and then Mara Jade kills them.
