How about giving her a subscription to a monthly book box club where she gets a new novel each month along with other book-related goodies? Another option could be purchasing signed copies of her favorite novels from various bookstores, or getting her a personalized book cover with her name on it. You could also consider taking her to a literary-themed trip like booking a stay at a bed and breakfast that was once home to a famous writer, or a trip to a city known for its literary culture like Paris or London.
Or you can get her a star map with an important date you share.
