Can you help find this story?

Hi guys, hoping someone can help me find this story.

From what I can remember, the story follows a young girl who goes away to a summer camp. Once there she is assigned to her cabin and meets her fellow cabinmates. She quickly discovers that a few of the cabin girls have been going to that summer camp for years and have started bullying and dominating the other girls in the cabin.

Any help much appreciated!

there are several with that theme... can you provide more info, perhaps the names of the girls involved?

Afraid not, it was quite a long time ago I came across it..
