Suggest my grandmother a book

My (80 +) grandmother has always been an avid reader, but lately she’s been having a hard time reading and she only read two or three books this year. She says her eyes can’t focus long enough.
I told her about audiobooks, and she loves the idea. I’m asking for general suggestions here, and I’ll see myself if they are available as audiobooks in French later. If there is an awesome suggestion that isn’t available as an audiobook… Well Christmas is near at hand and recording the book would be a great gift idea.

About her:
\- She loves life and is a powerhouse. She has an extremely positive view of the world and is extremely curious. Some of the subjects she finds especially interesting would be anthropology and biology. She also has a great interest for philosophy, but she has strong ideas so I never explored her taste there. Bear in mind that she is educated – she was a biochemist and worked in a nuclear program (as a woman in the 60s), and a lot of mainstream books wouldn’t work for her because of that.
\- The latest books I gave her and she loved where : Elena Ferrante (l’Amie Prodigieuse/Neapolitan Novels), Natassja Martin’s personal narration Croire aux fauves/In the Eye of the Wild and her anthropological research after that ; Agota Cristof’s L’Analphabète (about a woman fleeing a country and losing a part of what she is by losing daily touch with her native language – rebuilding a relationship with another language).
\- The last two hit close to home because she herself fled as a child during WWII, and was afterward raised in her second language (I never heard her speak her native Polish/Yiddish) and had to fight for education (her parents wanted her to leave school at 16 and her teachers didn’t think a woman should study sciences).
So if you guys can help me with suggestions to fill her life with books again, I would be extremely grateful!
