Books with happily single female protagonists (ideally 30+)

I read “Some Tame Gazelle” by Barbara Pym last year and really enjoyed it. It was excellent to read before bed because it was well written but not so exciting that it was impossible to put down and go to sleep. I also really loved that the two main characters were single, never married older women who had full lives and the point of the book wasn’t for them to be married off at the end. Any suggestions?
