Maybe? There are a lot of them and the quality varies depending on the book. You can’t go wrong with the original Thrawn Trilogy by Timothy Zahn. Heir to the Empire, Dark Force Rising, and Last Command were considered the unofficial sequel trilogy by some fans and they started off the entire Star Wars Expanded Universe, which got rebranded to the Legends continuity when Disney took over. Besides the Thrawn Trilogy, I’d also recommend the Revenge of the Sith novelization. I went in not expecting much, but it really expands on a lot of things the movie brushes over, and witnessing Anakin’s story from his viewpoint was a lot more compelling than what we got in the movie. From there, it really depends on what you want to read about.
The Star Wars book finder is a neat tool that lets you search by author, topic, or genre if you’re looking for something specific.
