When I taught 11th grade, I did the play 12 Angry Men. It’s totally clean (mayyyybe 1 bad word, just white it out when you make copies) and very fun for the girls to read. There’s also a black and white movie that goes with it, and it’s very clean, too.
I also did The Enemy of The People. There is maybe 1, 1.5 pages of “romance” that you can white out/skip, but I feel that calls too much attention to it. It is so innocent that I doubt most ppl would notice. However, there are so mild bad words that would need to be whited out.
Huck Finn was a lot of fun. That’s a classic that everyone does in 11th grade. Definitely do that.
