It's not easy to choose just one, but I can unhesitatingly name Jane Austen. She wrote about and from a time in England when women of high class had virtually no rights, the major ones lacking being the right to inherit a father's estate and the right to work and earn money. This set up some quite dramatic conditions for daughters, especially in families with no sons/brothers. The estate had to go to the father's closest male relative, even if that heir had never been known to him! Daughters had to either marry 'well' or depend on the generosity of the male heirs to care for them, which, in cases of unknown heirs, was quite a traumatic prospect, not to mention the tension of hoping to find a suitable husband, especially one that might include love in the mix! That was a major obsession, as one might expect. Mothers of daughters were especially solicitous of achieving this outcome!
Though it might seem that these are just aimed at women readers, that's far from so. The stories are strong and the male characters are fascinating. Austen, herself, was set to marry but it fell through. Her father was a pastor of a church, and a landowner, but without title. The family of her beloved didn't approve, which was another factor for women then. She was a rebel in that she decided to write professionally, in spite of the taboo against it. The rest is history, as they say.
The most famous of Austen's 6 novels is "Pride and Prejudice", which is a marvelous story. Austen's female heros are inevitably intelligent, witty, independent-minded (in spite of the limitations of the day), and interesting, as she, herself, was.
I have all 6 books and like them all, though not equally. I also have the film versions on DDV of each of them. I've 2 film versions of "Pride and Prejudice" and, though each has merit, the best is the BBC production.
The others (in order of my preferences) are:
Sense and Sensibility
