I’m a big fan of the Star Wars universe, but I haven’t been drawn in by many of the latest movies or TV shows (except The Mandalorian, of course. Wow, that’s fun). But books give another entry into that universe.
There are almost four hundred Star Wars books out there, covering a wide range of quality, from exceptional, to just embarrassing. There are also two timelines: the Canon books are the ones Disney has decided “really” happened in the Star Wars universe, and the Legends books, which are the majority of the older stories, written before Disney bought Lucasfilm.
I suggest you ignore whether something is Canon or Legends or not and just enjoy a good story in a great universe.
