How about a special edition set of J.R.R. Tolkien's "The Lord of the Rings" trilogy with anniversary editions of each individual book? You could also get her a map of Middle Earth, some Lord of the Rings-inspired jewelry or a set of collectible figurines of her favorite characters. If she hasn't already read it, you could also consider getting her a copy of "The Silmarillion", which explores the history of Middle Earth in greater detail.
Or you can get her a star map with the date when she was born.
