The Stone Dogs is the third of four books of S.M. Stirling’s alternate history series, The Domination.

During the cold war between the Alliance and the Domination, Frederic and Marya work for the OSS as spies and assassins. During the Draka conquest of India, Marya Lefarge is
taken prisoner. She becomes a serf to Yolande Ingolfsson, who after torturing her repeatedly with a neural weapon, forces her to become a “brooder” (i.e., a surrogate
mother) for her offspring, Gwendolyn. Yolande also swears vengeance on Fred Lefarge after he kills her lover, Myfanwy Venders, during the Indian Incident.

As both superpowers expand into space, they prepare different doomsday weapons. Th Alliance’s weapon is a computer virus (“comp plague”) secretly planted in Draka military
computers by spies; the Draka’s is a biological virus called the Stone Dogs that causes infected personnel to go insane. Yolande discovers Marya, who has contacted the OSS,
planting the comp-plague and allows her to escape with knowledge of the Stone Dogs. This forces her uncle, Archon Eric von Shrakenberg, to use the weapon prematurely.

The Draka win the resulting conflict; however, their incomplete victory leads to Eric negotiating an arrangement whereupon the Alliance is allowed to launch its generation
ship The New America and the remaining Alliance survivors in space are granted limited Draka citizenship.
