Classics recommendations for someone who didn’t like a lot of classics in school?

As stated in the title, what are some recommendations I can read now?

Out of all the classics I'd read, my favorites were The Giver, Huckleberry Finn, and To Kill A Mockingbird.

For The Giver, the setting and lifestyle presented engaged me from the start, since it was so strange, and as I continued reading, it never got boring. The realizations and pain the main character was going through, like realizing his family couldn't understand love or that his dad was killing babies, was compelling to me.

For Huckleberry, I enjoyed the adventure and characters, especially Huck, he seemed like an empathetic person and someone I would have wanted to be friends with. We had read Tom Sawyer in class a couple years before, but that book didn't really engage me the way Huckleberry Finn did.

With To Kill A Mockingbird, it wasn't as intense as the other two , it was more like a sweet read? I also liked the themes.

Besides those, I somewhat enjoyed Frankenstein, since I felt really bad for the creature, but some parts were quite slow. The teacher told us how the human and creature were foils to one another and I found that interesting, though I don't think I'd read a slow book for it.

I also somewhat enjoyed Brave New World, since the society was so strange, though it was a bit much at times. I particularly remember within the first few pages they describe a bunch of babies crawling then getting electrocuted. I also didn't feel as connected to the characters as I did with the characters in the other books, and would have preferred for more compelling characters.

Any recommendations?
