The second is an Usbourne lift the flap book See Inside Castles we also have the See Inside Your Body Book in this series, also excellent. There is a lot of info scattered through the books and it is written with a sense of humour, it even answers the question about toilets (I got sent out of class for asking what the toilets were like in a castle - do this day I don't understand why, it was a completely valid question)
I have just ordered another book, this time with stories of Knights, I will report back on that one when it arrives.
*Do you know about the Book Depository - it is excellent, I haven't bought anything through Amazon since discovering them. Not only are the books the same price or often cheaper than Amazon, the shipping is FREE yes, that is right FREE WORLDWIDE shipping. Several times I have ordered things from Amazon and it has taken weeks to arrive, a couple of times I have given up and cancelled the order and more than once they sent the wrong thing, well the Book Depository have yet to disappoint me!
