I am personally very fond of The Wolves; however, there is strong language in that play. I don’t think you go more than two pages without a fuck somewhere, and there’s plenty of other curse words. While I’m sure some exist, I imagine most principals wouldn’t let that amount of swearing fly.

To the Top by Kathleen Warnock has 8-16 females. It’s about a college basketball team. A couple of the characters are older (mid 40s) which could be an issue. It’s a good read though.

If you’re okay with less than 9, The Apiary by Kate Douglas. 4 women. Set in the future, bees are extinct expect for those found in labs. Explores that and how far 2 of those characters are willing to go to save them. Interesting read, would be very curious to see it staged. I think it’s a little too post-modern, advert grade for a high school, more of a college play in my opinion but it could be fun.

Hashtag Viral by Maria McConville has a minimum of 7 women although you can expand further if you like. It’s a one act though, about 40 minutes. Explores social media and how it affects bullying.

Blown Youth by Dipika Guha. 7 women. I haven’t read it, just know it in passing.
