I wish there had been such a specialist around to tell that to some of my HS English teachers :)
I faked my way through some of the high school reading, too. Classic novels weren’t written for teenagers. They’re “classic” because large numbers of adults bought them and read them, voluntarily. Some younger people will like some books - I loved “Pride and Prejudice” in high school - but many will be put off a lot of great writers.
I’ve been reading novels by Willa Cather and Henry James in the last few months, and I’m about to hit the library for more Edith Wharton, as soon as I finish the biography of her I checked out yesterday. I did like “Ethan Frome” as a teen, but nobody else in my literature class did!
