How about a special edition boxed set of Stephen King novels or a signed copy of one of his books? You could also consider getting her tickets to a Stephen King book signing event, or a subscription to a Stephen King book club. Another idea could be to create a Stephen King themed gift basket with items like a King-inspired mug, t-shirt, or even a bookmark. Finally, you could consider getting her a Stephen King writing class, either in-person or online, so she can learn how to write her own horror stories.
Or you can get her a star map with an important date you share.
