Jane Austen's Emma.
And I have been enjoying it a great deal. It must be well over a decade ago since I first read it, but I do not remember it being this good. Chalk it up to my being a blasé and aloof teenager at the time...
I remember recommending a re-reading of Austen a couple of years ago when you were seeking a new suitor. As you say, you weren't so keen back then.

I'm still working my way though The Kindly Ones. As yet I remain unconvinced of its merits, maybe it's better in the original.
