I hadn’t actually considered that. I’ve read 3 of the books on the top 5, and think they’re great books. But all of them have been made into TV shows now, which could explain it. Catch 22 is probably my favourite book of all time, but it’s long and kinda disorienting to read (every chapter is out of order, except for the last one). I guess it makes sense people would pick it up after watching the TV show, and then give up on it.
