I also really liked The Rules of Civility. I've been trying to get through A Gentleman in Moscow for some time and am having trouble getting into it (although many people I know really love it), and I found Rules of Civility a much more enjoyable read for some reason.
And agree with previous posters who recommended Crazy Rich Asians - the first was the best but the other two in that series were also enjoyable - Katie FForde, the Outlander series (I found some of the books in the middle started to drag for me, but the first two especially I thought were great), and Georgette Heyer for excellent fluff. I could reread Cotillion alone so. many. times. And the Little Lady Agency series by Hester Browne was a fun read!
I also like M. M. Kaye, if you're up for some long novels, or her mysteries are shorter. Trade Wind is one of my favorite books of all time, and it's set in mid-19th C Zanzibar which was a fascinating setting to me.
Finally, just about anything by Meg Cabot. Including her YA fiction. She is so freaking funny.
