Beyond the Thrawn Trilogy and Hand of Thrawn Duology, I'd recommend I, Jedi and the Corellian Trilogy.
Of course, there are also books I'd recommend you avoid. Pretty much any novel written by Kevin J. Anderson -- especially the Jedi Academy Trilogy -- should be steered clear of at all costs. Oh, and Death Troopers, too; I consider it one of the worst -- if not the worst -- novel I've read from the EU.
