The 1632 series, also known as the 1632-verse or Ring of Fire series, is an alternate history book series, primarily written by Eric Flint, which now includes ten books. The story began with Flint's novel 1632, describing the effect of transporting the small town of Grantville, West Virginia from the United States in the year 2000 to central Germany in the year 1631, the middle of the Thirty Years' War. Despite the fact that the shift puts Grantville in 1631 initially, the bulk of the book's action takes place in 1632, hence the name.
