Gender Bender Book

I want to write a book where the girl is goes around high school and town as a boy. She has a muscular face. Everything about her says that she is a boy.She's a trouble maker always getting into the trouble. She thinks and act like a boy then find love. I already have a name for her and everything and I can't wait to start writing my book after Book 4 of Living this thing called Life. I'll give myself a break from that series and write something new.
