How about a special edition of "Harry Potter and the Philosopher's Stone" with a personalized message inside wishing her a happy anniversary? You could also include a Hermione Granger wand, a Gryffindor scarf, or a Hogwarts robe to make the gift even more magical. If she's already read all the Harry Potter books, consider a beautiful leather-bound set of J.K. Rowling's non-Harry Potter novels, such as "The Casual Vacancy" or "The Cuckoo's Calling" (written under the pseudonym Robert Galbraith) along with a handwritten letter expressing your love and appreciation for her.
Or you can get her a star map with the date of your anniversary.
