I desperately need help finding this book I read probably a decade ago. I can't remember any character names but i know that the mc was a teen girl who sorta lived in some sort of theater and I think and she wanted to find her mom or the truth about her mom but her guardian/parent person wouldn't let her but she leaves anyway. She also has two or three fairies that hang with her all the time and I think they're might have been something with a merman. I literally cannot stop thinking about this God forsaken book someone help please.
