Looking for a Story

A while back there was a story I read that I don't remember the name of and I wanted to go back and read again.

The beginning of the story starts with a kid at if I remember correctly an All Boys Boarding school or some form of an All Boys school and the main character is preparing to leave because their body is turning itself into a girl.

The main character gets into some art/Music college and eventually becomes a famous singer.

Thats all I honestly remember about the story. I hope thats enough for you guys to point me in the right direction for the story.
