Frances (1915-2013) and Joseph (1916-2006) Gies were the world's bestselling historians of medieval Europe. Together and separately, they wrote more than twenty books, which col-lectively have sold more than a million copies. They lived in Michigan.
"Some particular books I found useful for A Game of Thrones and its sequels deserve mention. ... Life in a Medieval Castle and Life in a Medieval City, both by Joseph and Frances Gies." -- George R.R. Martin, author of the A Song of Ice and Fire series "The Gieses succeed in making a remote and unfamiliar world accessible." -- Kirkus Reviews "The authors allow medieval man and woman to speak for themselves through selections from past journals, songs, even account books." -- Time
