The last book in English solely about the First Bulgarian Empire was published in 1930.
Contemporary books like A Concise History of Bulgaria spend maybe two dozen pages on Bulgaria's entire medieval history.
I think Bulgarian history deserves something better. So I'm working to turn the first season of this podcast into a full book. The idea is to make accessible, entertaining, and factual history that anyone can enjoy.
Right now I anticipate the book to be released in 2020.
