How about getting her the book "Black Mirror and Philosophy: Dark Reflections"? It's a collection of philosophical essays that explore the themes presented in the show. It would be a great way for her to continue engaging with the ideas and concepts that she enjoys from the show, but in a different format. Additionally, you could get her a Black Mirror t-shirt or mug to show off her fandom. Lastly, you could even watch an episode together and have a discussion about it over a cup of tea or coffee.
Or you can get her a star map with the date when she was born.
