The Game of Kings by Dorothy Dunnett
"That is the Dunnett effect - there are thousands of readers who now eagerly read about such diverse topics as Scottish 15th century coinage, Russian politics and the trading effects of Alum mining and dyeworking on Renaissance Europe, who might never have known some of these things existed. People scour art galleries looking for pictures of Venetian bankers and Brussels traders, or seek out the Icelandic Sagas to broaden their understanding of an ancient king who was later “framed” by Shakespeare. We are all immensely broadened in our outlooks and knowledge of the world - and all while enjoying a series of books from which we’ll still be discovering new surprises long into our old age."

NEVERMIND. I'm sorry, I should have checked audible.com before I posted. They don't seem to have it unless I'm searching incorrectly. I just assumed they did because they have everything else I've looked for and I knew it was available.
