The next book in my book club is Little Women. I must have read it a dozen times, starting when I was 10 or 12. I love the story, though for different reasons every time.
It's also an excuse to watch the movies again. Just scanning the older adaptations makes me appreciate the latest one from Greta Gerwig and its wickedly entertaining feminism. (Its major flaw is that the Professor is entirely too young.)
@KarenSohne I find it really different to read as an adult. Maybe just "looking forward" vs "looking back."
