Imagine you could travel back to the fourteenth century. What would you see, and hear, and smell? Where would you stay? What are you going to eat? And how are you going to test to see if you are going down with the plague?

History is not just something to be studied; it is also something to be lived, whether that's the life of a peasant or a lord. The result is perhaps the most astonishing history book you are ever likely to read; as revolutionary as it is informative, as entertaining as it is startling.
