In Flint's novel of time travel and alternate history, a six-mile square of West Virginia is tossed back in time and space to Germany in 1632, at the height of the barbaric and devastating Thirty Years' War. Repelling marauding mercenaries and housing German refugees are only the first of many problems the citizens of the tiny new U.S. face, problems including determining who shall be a citizen. In between action scenes and descriptions of technological military hardware, Flint handles that problem and other serious ethical questions seriously and offers a double handful of memorable characters: a Sephardic Jewish family that establishes commercial and marital ties with the Americans, a cheerleader captain turned lethal master sniper, a schoolteacher and an African American doctor who provide indispensable common sense and skill, a German refugee who is her family's sole protector, and, not least, King Gustavus Adolphus of Sweden.
