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. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...

NO ONE COULD STOP THEM—NOT STALIN, NOT TOGO, NOT CHURCHILL, NOT ROOSEVELT . . . The invaders had cut the United States virtually in half at the Mississippi, vaporized Washington, D.C., devastated much of Europe, and held large parts of the Soviet Union under their thumb. But humanity would not give up so easily. The new world allies were ruthless at finding their foe's weaknesses and exploiting them. Whether delivering supplies in tiny biplanes to partisans across the vast steppes of Russia, working furiously to understand the enemy's captured radar in England, or battling house to house on the streets of Chicago, humankind would never give up. Yet no one could say when the hellish inferno of death would stop being a war of conquest and turn into a war of survival—the very survival of the planet . . .

Communist China, Japan, Nazi Germany, the United States: they began World War II as mortal enemies. But suddenly their only hope for survival—never mind victory—was to unite to stop a mighty foe—one whose frightening technology appeared invincible. Far worse beings than the Nazis were loose. From Warsaw to Moscow to China's enemy-occupied Forbidden City, the nations of the world had been forced into an uneasy alliance since humanity began its struggle against overwhelming odds. In Britain and Germany, where the banshee wail of hostile jets screamed across the land, caches of once-forbidden weapons were unearthed, and unthinkable tactics were employed against the enemy. Brilliantly innovative military strategists confronted challenges unprecedented in the history of warfare. Even as lack of fuel forced people back to horse and carriage, physicists worked feverishly to create the first atomic bombs—with horrifying results. City after city joined the radioactive pyre as the planet erupted in fiery ruins. Yet the crisis continued—on land, sea, and in the air—as humanity writhed in global combat. The tactics of daredevil guerrillas everywhere became increasingly ingenious against a superior foe whose desperate retaliation would grow ever more fearsome. No one had ever put the United States, or the world, in such deadly danger. But if the carnage and annihilation ever stopped, would there be any pieces to pick up?

At the bloody height of World War II, the deadliest enemies in all of human history were forced to put aside their hatreds and unite against an even fiercer foe: a seemingly invincible power bent on world domination.With awesome technology, the aggressors swept across the planet, sowing destruction as Tokyo, Berlin, and Washington, D.C., were A-bombed into submission. Russia, Nazi Germany, Japan and the U.S. were not easily cowed, however. With cunning and incredible daring, they pressed every advantage against the invader's superior strength, and, led by Stalin, began to detonate their own atom bombs in retaliation. City after city explodes in radioactive firestorms, and fears grow as the worldwide resources disappear; will there be any world left for the invaders to conquer, or for the uneasy allies to defend? While Mao Tse-tung wages a desperate guerrilla war and Hitler drives his country toward self-destruction, United States forces frantically try to stop the enemy's push from coast to coast. Yet in this battle to stave off world domination, unless the once-great military powers take the risk of annihilating the human race, they'll risk losing the war. The fatal, final deadline arrives in Harry Turtledove's grand, smashing finale to the Worldwar series, as uneasy allies desperately seek a way out of a no-win, no-survival situation: a way to live free in a world that may soon be bombed into atomic oblivion.

In the extraordinary Worldwar tetralogy, set against the backdrop of the World War II, Harry Turtledove, the "Hugo-winning master of alternate SF" (Publishers Weekly), wove an explosive saga of world powers locked in conflict against an enemy from the stars. Now he expands his magnificent epic into the volatile 1960s, when the space race is in its infancy and humanity must face its greatest challenge: alien colonization of planet Earth. Yet even in the shadow of this inexorable foe, the United States, the Soviet Union, and Nazi Germany are unable to relinquish their hostilities and unite against a massive new wave of extraterrestrials. For all the countries of the world, this is the greatest threat of all. This time, the terrible price of defeat will be the conquest of our world, and perhaps the extinction of the human race itself.

In 1942 Hitler led the world's most savage military machine. Stalin ruled Russia while America was just beginning to show its strength in World War II. Then, in Harry Turtledove's brilliantly imagined Worldwar saga, an alien assault changed everything. Nuclear destruction engulfed major cities, and the invaders claimed half the planet before an uneasy peace could be achieved. A spectacular tale of tyranny and freedom, destruction and hope, Colonization takes us into the tumultuous 1960s, as the reptilian Race ponders its uneasy future. But now a new, even deadlier war threatens. Though the clamoring tribes of Earth play dangerous games of diplomacy, the ultimate power broker will be the Race itself. For the colonists have one option no human can ignore. With a vast, ancient empire already in place, the Race has the power to annihilate every living being on planet Earth . . .

Set in the same universe as the Worldwar series, Colonization: Aftershocks brings us to Earth in the 1960s, where four superpowers rule: the United States, Russia, Nazi Germany, and the aliens of the Race. The arrival of the aliens shot Earth technology forward at a dizzying rate—the world of 1960 includes routine space shuttle traffic, computers on every desk, and other high tech advancements. Aftershocks reveals that it was the United States that launched the nuclear offensive against the aliens, and when the aliens learn the truth, Indianapolis disappears in nuclear fire. In alien-held China, a full-fledged rebellion is launched, and in Poland, a nuclear bomb goes missing—held by Jewish forces who seek to use it against the Nazis.The nations of Earth begin to realize that their only hope in holding back the aliens will be to work together. Because separately, they may face extinction. About the Author: Harry Turtledove is a Hugo Award-winning and critically acclaimed writer of science fiction, fantasy, and alternate history.

The twentieth century was awash in war. World powers were pouring men and machines onto the killing fields of Europe. Then, in one dramatic stroke, a divided planet was changed forever. An alien race attacked Earth, and for every nation, every human being, new battle lines were drawn. HOMEWARD BOUND With his epic novels of alternate history, Harry Turtledove shares a stunning vision of what might have been–and what might still be–if one moment in history were changed. In the WorldWar and Colonization series, an ancient, highly advanced alien species found itself locked in a bitter struggle with a distant, rebellious planet–Earth. For those defending the Earth, this all-out war for survival supercharged human technology, made friends of foes, and turned allies into bitter enemies. For the aliens known as the Race, the conflict has yielded dire consequences. Mankind has developed nuclear technology years ahead of schedule, forcing the invaders to accept an uneasy truce with nations that possess the technology to defend themselves. But it is the Americans, with their primitive inventiveness, who discover a way to launch themselves through distant space–and reach the Race’s home planet itself. Now–in the twenty-first century–a few daring men and women embark upon a journey no human has made before. Warriors, diplomats, traitors, and exiles–the humans who arrive in the place called Home find themselves genuine strangers on a strange world, and at the center of a flash point with terrifying potential. For their arrival on the alien home world may drive the enemy to make the ultimate decision–to annihilate an entire planet, rather than allow the human contagion to spread. It may be that nothing can deter them from this course. With its extraordinary cast of characters–human, nonhuman, and some in between–Homeward Bound is a fascinating contemplation of cultures, armies, and individuals in collision. From the novelist USA Today calls “the leading author of alternate history,” this is a novel of vision, adventure, and constant, astounding surprise.
