Short books/novellas for an 80-something year old who hasn’t read in decades and doesn’t have a great memory?

I want to try to encourage my grandma to start reading to help keep her mind active! Any ideas?

Uncomplicated narratives, straightforward plotting and nothing that requires too much (wellll, any really) pop-culture knowledge, and could be read in a sitting or two. Maybe 200 pages at most, though as long as it’s an easy read I guess it’s ok if slightly longer.

I don’t know any other similar books to compare the ideal vibe to, but anything heartwarming or charming, especially in that very middle class British way that a lot of older people seem to enjoy lol like movies like Allelujah, The Great Escaper, The King’s Speech type of thing.

Thanks in advance!
