How about a book on ethnographic studies? "Cultural Anthropology: Appreciating Cultural Diversity" by Conrad Phillip and James Spradley would be a great recommendation. Alternatively, you could look for a subscription to a magazine that she would enjoy reading, such as "Cultural Anthropology" or "Ethnography." Another idea is to enroll her in a workshop or seminar with an ethnographer or anthropologist in your area. This would provide a unique learning experience and allow her to engage with people who share her interests.
Or you can get her a star map with the date when she was born.
