As a general rule, I'd say no.
However, I have read two series of Star Wars novels, X-Wing and Republic Commandos.
What set those apart in my mind is the fact that both series took place entirely separate from events of the games/movies they share a universe with.
X-Wing takes place after the Star Wars movies end, and follow an entirely new set of characters through the aftermath of the Galactic Civil War. Just because the leadership was dead and the superweapon was destroyed didn't mean that everything was over. There was the power vacuum that the Republic had to quickly fill, and all of the remaining forces of the Empire to contend with. It was also nice to get some Star Wars material that was somewhat grounded. There's still Jedi in the series, but there are far more fighter pilots, politics and cunning plans on display than Jedi mind tricks or lightsabers.
As for Republic Commandos, it starts off with a different set of commandos than the ones featured in the game and takes a very interesting direction. The series focuses on the culture developed by the clones during the clone wars, and has an interesting side plot involving a female jedi and one of the commandos. They become romantically involved over the course of the first book, and both have to deal with the fallout involved in that decision in consecutive books. The Jedi has to wrestle with her conscience, while the clone commando is confronted with his own mortality. He realizes that even though he's found something worth living for, he'd never live long enough to see his son grow up. If he didn't die on the battlefield, his accelerated aging would give them a decade or so before his body decayed and he died. It was really interesting watching the characters work through these things, while the rest of the squad try to keep things running smoothly. The relationship becomes everyone's problem, because they all still have to work together to break up terrorist cells and overthrow Separatist planetary governments.
I also remember reading a book about a squad of Stormtroopers as they progress from young idealists through boot camp and into the questionable conflict. It was kind of neat to see the Empire from a more positive point of view, and explore how people with good intentions could get moved around through the conflict. Each squad member has their own moral dilemma once they start seeing the reality of working for the Empire, and the squad leader has the added burden of trying to keep everyone alive while also deciding where his loyalty lies (also, by extension, the loyalty of his squad). There may have been more books in the series, though I don't think they were released at the time and I haven't gotten around to buying them.
So yeah.
TL;DR: I don't always read books based on other properties, but when I do, it's usually something Star Wars-related, exploring different aspects of the universe.
