This is a fairly recent book, having had my hands on it sometime between 1996-1998.  It was definitely a picture book.  I can’t remember if the classroom copy was paperback or hardcover, but I don’t think the book was published any time before 1985 and it was more likely to have been put out after 1992.

My clearest memory is of a page showing a slim girl with cropped black hair who, as a thief, had a magical belt or girdle that made her invisible.  The belt may have been silver.  The story took place in an imaginary land or in the past; I think she was dressed in a very sort of medieval page way.

I am certain there were other girls with other specific talents and magical objects in the book, but I am unsure as to how many.  Judging from trends in children’s literature it was probably 3 or 7.

Thank you so much!
