This is a really long shot, as I can't remember any actual specifics about the book. I remember that it was about a number of sisters, maybe 5 or 6 of them, who all lived in a house together. I remember that the main point of the book was that they loved each other and always took care of each other (there were no parents around for whatever reason)... I seem to recall it having really pretty pictures in it.
But I last read it when I was five or so. Anyone have any ideas?
