Despicable Girls

Patty, the older sister of Margo, Agnes, and Edith joins them on a journey into adoption by a fellow named Gru who has a strange affect on the sisters. Agnes is attached to him, Edith finds him interesting, Patty doesn't seem that interested in him at all, and Margo seems to feel the same way. Can they all get along? Sorry, I suck at summaries, story should be a whole lot better.
