Eric Flint was the creator of the New York Times best-selling Ring of Fire series, the best-selling alternate history series of all time. Beginning with 1632, Flint—along with dozens of cowriters—chronicled what happened when the 20th-century town of Grantville, West Virginia, was transported through time and space to 17th-century Europe. In addition, Flint was the author, with New York Times best seller David Weber, of the Crown of Slaves Saga, as well as the Belisarius series with best-selling author David Drake. Flint was the editor of Jim Baen’s Universe, as well as numerous short story anthologies. Before becoming a writer, Flint worked as a trade union organizer, longshoreman, truck driver, auto worker, steel worker, oil worker, meatpacker, glassblower, and machinist. Eric Flint passed away in 2022.

David Drake is widely regarded as America's foremost exponent of military and historical science fiction. His bestselling books include the HAMMER'S SLAMMERS series and the Belisarius novels co-authored with S.M. Stirling and with Eric Flint.
