Ring of fire IV

Summary/Review: "A cosmic accident--the "Ring of Fire"--has transported the 20th century West Virginia town of Grantville through both time and space, into the heart of Germany during the Thirty Years War. After fending off attacks from various hostile European powers, the time-lost Americans have allied themselves with the Swedish king Gustavus Adolphus to form the United States of Europe. For better or worse, the course of history has been radically altered. Now top writers continue to expand the saga with all new stories by Hugo and Nebula award winner David Brin, Eric Flint, Charles Gannon, Virginia DeMarce and many others"--
