Elsa Aren the Queen of Arendelle. She has a sister named Anna Aren. She once froze her heart but thawed it with love. Jack Frost the guardian of fun, or he use to be. When he lost the battle with pitch he became dark and cold hearted. But that all changed when he saw a girl and thought; I must have her and i will have her. If u want to know what happens then u must read my book! :). This is after the whole freezing Arendelle thing. It might be +13 at times.
