I love Usborne products, and I think this could be a great tool for teaching Arthurian legends (to older children). I knocked a couple of stars off my rating because, unfortunately, Usborne did not supply an age rating on this book, and it really needs one. I bought this for a 3.5 year old who is learning about English history, Arthurian legend and the knights of Camelot, (in a very gentle way.) I thought the book might be a way to supplement his "knight play", but *be warned*, the subject matter is very, very violent and much too mature for a little man. The content doesn't talk much about the code of honour in Arthur's kingdom or among his knights, and deals a lot with beheading green giants and such. I found it much too graphic. I would think, given the level of violence, (OK, to be fair, knights fight and a certain level of violence might be expected) this should be rated at least 8 years old +. That said, I will hang onto the product until my little knight is older, and I would highly recommend other Usborne books on the subject of castles. My little knight thinks the Usborne "What Were Castles For?" book is king, and I loved the links that (the latter book) gave to working castles and castle ruins.
