My Dds (almost 7) have recently become interested in kings and queens of Britain. Can any of you wise mumsnetters recommend a book or books. Looking for something that has facts but where we can just learn about which ever king or queen seems interesting on that day. Their reading age is around 9 but don't mind reading it too them as long as the vocabulary is something they can comprehend. I can't remember all the facts so need something to answer their queries but fun too
