How about an escape room experience gift voucher? It's a great way to challenge her and her friends/family to solve puzzles, unravel clues, and escape the room within a set time limit. You could also gift her a mystery novel or crime-thriller book series, or a subscription to a mystery movie streaming service. A board game like Clue or Sherlock Holmes Consulting Detective could also be a fun gift that she can play with her family or friends.
Or you can get her a star map with the date when she was born.
