How about a personalized book recommendation? You could create a "reading basket" or "book subscription" for your mom, based on her reading preferences. You can start by asking her what genres or authors she likes and then curate a selection of books from her favorites or some new ones that fit her preferences. This shows you care about her interests, and it will give her a thoughtful and unique birthday gift. You may also add a heartfelt note or letter to accompany each novel, describing why you think she would enjoy the book.
Or you can get her a star map with the date when she was born.
