This is the seventh and last book of the Time Patrol - Nancy Laplante series. From the streets of 1854 London to the battlefields of the Crimean War to the French siege lines around Maastricht in 1673 and to the besieged Paris of 1870 during the Franco-Prussian War, Nancy Laplante 'B', a young field agent of the Time Patrol continues with her missions in the 17th and 19th Centuries, finding both adventure and love, but also heartbreak. In Timeline 'C', a parallel line to the original historical timeline, Ingrid Dows is in charge of the American space program and is also a very influential presidential advisor. She also has many enemies, who are jealous of her power and influence. While dodging bullets, missiles and political daggers, Ingrid will lead the United States into space.
