Advice needed for reader new to Star Wars

tightwad thought this was worth mentioning said

Every christmas (when we remember) we gift our kids with a book they can enjoy on Christmas eve. This year my son (17), who has a tough time reading due to disgraphia, requested Star Wars books. I think he wants the books that relate to the movies but looking at Wookiepedia the book list is a bit…enormous. How can I get a good novel/series that isn’t all 6 million different titles? Looking for books that tie back to the movies…but not books made from movies (which is just annoying).

Any help?
