Query: A refreshing mystery for all ages

I just finished reading the book cover to cover. It is a very refreshing mystery that provides history lessons that some young adults may not be provided in school anymore.The characters are clever and it shows young girls that they can do anything they set their minds to.It is a wonderful book and it should be on all teacher's and parent's lists. A wonderful gift idea.
