Summerlove and winterhearts

Elsa, Anna, Jack, Rapunzel, Merida, Hiccup, Kristoff and Eugene all live in different countries (except from Anna and Elsa who are sisters), but they meet every year at Summer Camp in Norway. (camp halfblood-style, but this isn't a crossover so the gods doesn't exist, okay. and the pjo characters aren't there.) They have gone there for four weeks every summer since they were 8 and 9. (Not all of them are born the same year) This fic will start the first summer,but i don't think all of the summers will be there, but maybe flashbacks, okay? Okay.
