The folks at Book Riot call it 'genre kryptonite' and I love that phrase, even if you might think it means something else.
Basically, 'genre kryptonite' is anything that you are powerless to resist and love to read about.
Here's one of mine:
Intentional Communities/Communes. Especially if they feature crazy hippies who do lots of drugs and try to be idealistic without having any sort of structure.
Drop City by T.C. Boyle is a favorite.
Right now, Arcadia by Lauren Groff is hitting this mark so well. Mmmm...
I will take any other titles you can recommend on this topic; whether they are fiction or nonfiction or memoir is of no consequence.
