Don't spend your money on this book - it is poorly researched, with straightforward mistakes and lies about the history of Bulgaria. Example: the magic mountain of Orpheus is not Haemus (the Balkans), but Rhodope. This is elemental classical history scholarship, which completely lacks in the book. On the top of it, it is politically biased. Get the book "Bulgaria" by Crampton and you will learn more about the history of the Bulgarian lands, better written and more useful overall.
