Anyone who is disappointed with the sequel trilogy (which seems to be most people) should read the Heir to the Empire trilogy from Timothy Zahn.
I read it in high school and again after college and it still held up as a fun, cohesive, Star Wars trilogy. Maybe I'll read it again this year. It was written in the 90's and is set shortly after RotJ, so you have the original Star Wars cast back as your primary protagonists, plus some great new characters and a villain so good they actually lifted him into the Rebels TV show as a primary antagonist.
Folks disappointed in the sequel trilogy might enjoy it.
Thanks and gig'em
