Which would you choose?

This is for a fanfiction I wanted to write for a while, I already started it and I will post the first chapter here if you wish but I need a little help. The story is about how one character got a book that would put all the people she knows into a fairytale she chooses. Another character wants her to use it to pair her with a guy she likes. Anyway she doesn't do that but she does read the book. But I was wondering what fairy I should do, or if it should be a series of fairytales and if so which is first? So I was hoping you guys can tell me what you think it should be. Please.
