War seethed across the planet. Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...the fate of the world hung in the balance. Then the real enemy came.

In the extraordinary Worldwar tetralogy, set against the backdrop of World War II, Harry Turtledove, whom Publishers Weekly has called the "Hugo-winning master of alternate SF," wove an explosive saga of world powers locked in conflict against an enemy from the stars.

January 1864: General Robert E. Lee faces defeat. The Army of Northern Virginia is ragged and ill-equipped. Gettysburg has broken the back of the Confederacy and decimated its manpower. Then, Andries Rhoodie, a strange man with an unplaceable accent, approaches Lee with an extraordinary offer. Rhoodie demonstrates an amazing rifle: its rate of fire is incredible, its lethal efficiency breathtaking - and Rhoodie guarantees unlimited quantities to the Confederates. The name of the weapon is the AK-47.

The New York Times best-selling master of alternate history delivers the captivating first novel in his new World War II series. Harry Turtledove imagines how the war in Europe would have ended had British prime minister Chamberlain refused to allow Hitler's annexation of the Sudetenland.

In the chaos that ensues, thousands are killed, but the maelstrom has only just begun.

Humanity has colonized the planets - interstellar travel is still beyond our reach, but the solar system has become a dense network of colonies. But there are tensions - the mineral-rich outer planets resent their dependence on Earth and Mars and the political and military clout they wield over the Belt and beyond.

Captain Keyes is loved by the public but hated by Command. He captains the UHS Providence, an aging supercarrier and the last human ship not dependent on dark tech - technology humanity has used to rule over the galaxy since barely defeating the Ixa in the First Galactic War.

William Mandella is a soldier in Earth's elite brigade. As the war against the Taurans sends him from galaxy to galaxy, he learns to use protective body shells and sophisticated weapons.

The Zombie War was the longest and most costly conflict that Britain has ever waged. No one knows the true figure of those who lost their lives in the long years of the war and tragically too many have lost their lives in the years of peace that have followed. Life expectancy is a shadow of what it was and many diseases and ailments that science thought it had eradicated have returned. Many of those who survived the war have since died, taking with them the stories and memories of the most devastating and important struggle that mankind has ever waged.

In the twentieth century Earth sent probes, transmissions and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy.
