The New Novel in the New York Times Best-Selling Series. Eric Flint, the Reigning Master of Alternate History, Returns to the Series He Created in 1632 for the Most Exciting Entry Yet in the Ring of Fire Saga.             The Thirty Years War continues to ravage 17th century Europe, but a new force is gathering power and influence: the United States of Europe, a new nation led by Gustavus Adolphus, King of Sweden, and the West Virginians from the 20th century led by Mike Stearns who were hurled centuries into the past by a mysterious cosmic accident.       While the old entrenched rulers and manipulators continue to plot against this new upstart nation, everyday life goes on in Grantville, even under the shadow of war, as this lost outpost of American freedom and justice must play David against a 17th century Goliath of oppressive feudalism.   Praise for the New York Times Best-Selling Series: “. . . gripping and expertly detailed . . . a treat for lovers of action-SF or alternate history . . . battle scenes depicted with power . . . distinguishes Flint as an SF author of particular note, one who can entertain and edify in equal, and major, measure.” — Publishers Weekly (in a starred review)   “[This] alternate-history saga . . . is certainly a landmark in that subgenre. . . .
