The Great War: Breakthroughs(The Great War‪)‬

The Great War: Breakthroughs is the third installment of bestselling, Hugo Award–winning author Harry Turtledove’s remarkable alternate history tetralogy. A Main Selection of the Science Fiction Book Club®, this harrowing saga of the war to end all wars will amaze history buffs and fans of science fiction and fantasy.
The utter devastation of global war continues to spread, driven by new weapons and old hatreds. The United States is deadlocked—battling Canada and Great Britain in the north and the Confederate States in the south. In this world, military genius is tantamount to madness, as great historical figures like Theodore Roosevelt and Custer engage in fascinating new tactical scenarios.
History professor Turtledove’s highly imaginative novels are hailed by critics and readers alike as the defining works of their genre.
“Alternate history’s grand master displays his acute knowledge of American history as well as his keen imagination as he paints a vivid portrait of a past that could have been. A good choice for most libraries.”—Library Journal
