I have, over the years, read and reread, the first few (maybe 5?) books in Winston Graham's Poldark series. There are 11 altogether, and I've recently managed to snag the rest of the books, so I was all set to read them when a copy of Longbourn came in at the library on a 7-day checkout (no renewals).
So I quickly changed my plans and dove into Longbourn by Jo Baker. I was not disappointed. It's Pride and Prejudice (sort of) told from the viewpoint of the servants in the Bennet household. So, it's less about the Bennets and more about the lives of those servants, in particular, Sarah, a young woman who had come to the household as a child but is now grown. I'm not sure I can ever read Pride and Prejudice with the same blithe disregard for the shadowy servants in the book again, but I highly recommend Longbourn.
