Sailing to Sarantium was my first Guy Gavriel Kay book, and it won't be my last. Not just that it didn't wrap up in one book (boo! … kidding), I also enjoyed the style a lot. Kay lets his story take place in Byzantium during Constantine's reign. It's not called Byzantium to allow for some creative freedoms and minor magic, but everything very clearly maps 1:1 to historic characters.
