Here are few gift ideas based on your friend's interests:
1. Box Set of Tolkien books: A box set of all four parts of "The Lord of the Rings" or "The Hobbit" is a perfect gift for a Tolkien fan. Your friend will love to own and read these great works by J.R.R. Tolkien.
2. Map of Middle-earth: Your friend may appreciate a well-crafted map of Middle-earth, which can either be framed or used as a decorative piece in her/his room.
3. Bookmarks: Personalized bookmarks featuring her/his favorite Tolkien characters or quotes can also be a great gift. There are many online shops that offer custom-made bookmarks relating to "The Lord of the Rings" and "The Hobbit."
4. Collectibles: There are many collectors' items available based on J.R.R. Tolkien's works, such as figurines of famous characters, jewelry, puzzles and posters.
5. Special edition book: You can gift your friend a special edition of "The Lord of the Rings" trilogy, which comes with extra content, illustrations and annotations. This is a great gift if your friend already owns the books, but would enjoy the added value that comes with a special edition.
