Need beta readers!

Hey y’all!
I need at least 5 beta readers (can be 3) to help me with Grammar and vocabulary (don’t know if it’s the same as grammar).

I’m Brazilian and I wrote this story called Survivors which is about an apocalypse. I have a very deep knowledge about English but still I’m insecure!
I can’t promise to help you the same way but I can help reading and telling if your story has a connection and makes sense, also maybe make a background/overlay.

If you’re interested in helping me, please send a private message or Dm through Instagram: writer_tathiana
