While the Thirty Years War, rages on, there is a new force to reckon with in central Europe: the Confederated Principalities of Europe, an alliance between King Gustavus of Sweden, and the West Virginians led by Mike Stearns who were hurled into 17th century Germany by a mysterious time warp. As the greatest naval war in Europe's history erupts, Mike's wife Rebecca is trapped in war-torn Amsterdam, and Mike's sister Rita and Melissa Mailey are prisoners in the Tower of London. But Rebecca has courageous and battle-hardened assistants, while Melissa and Rita know that Julie and Alex MacKay are visiting Alex's family in Scotland. And Julie, an Olympic-class crack shot, has her Twentieth Century rifle.
