I need a good book about Medieval Greece, covering the 10th and 11th centuries. I don't seem to be able to find one. Everyone is absolutely fascinated by ANCIENT Greece. I can get all the books on that time period I could want. In fact, I have tons. But nobody seems to know what the Greeks were up to circa 1066 or so. I mean, they must have been doing something. Didn't anyone write it down?
