Just watched Star Wars: Return of the Jedi- what's next?

So I just finished watching all the Star Wars films for the first time and I was wondering, whats comes after "Return of the Jedi" in terms of the story? Where would be the best place to start? There are so many books based on the film- prequels and sequels- but I want to continue on one that takes place directly after the events of the last movie, then go on from there.
