Thanks for sharing all these lists. I'm reading the Mapp and Lucia books now, thanks to the multiple recommendations. And I love them
For some reason. I struggled a bit last year to find new books to read and ended up re-reading quite a few. But here were the new ones (to me) I did read and enjoyed a lot:
The Martian by Andy Weir
The Custom of the Country by Edith Wharton
The House of Mirth by Edith Wharton
and the best re-read:
Lord of the Flies by William Golding
Mapp and Lucia fans -- take note of the Edith Wharton novels. They aren't quite as light and fun, but have the same ironic viewpoint on social mores.
