Set in the same universe as the Worldwar series, the Colonization series brings us to Earth in the 1960s, where four superpowers rule: the United States, Russia, Nazi Germany, and the aliens of the Race.

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.

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.

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.

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.

In Harry Turtledove's mesmerizing alternate history of World War II, the choices of men and fate have changed history. Now it is the winter of 1941. As the Germans, with England and France on their side, slam deep into Russia, Stalin's terrible machine fights for its life. But the agreements of world leaders do not touch the hearts of soldiers. The war between Germany and Russia is rocked by men with the courage to aim their guns in a new direction. England is the first to be shaken.

In 1938, two men held history in their hands. One was Adolf Hitler. The other was British prime minister Neville Chamberlain, who, determined to avoid war at any cost, came to be known as "the great appeaser". But Harry Turtledove, the unrivaled master of alternate history, has launched a gripping saga that springboards from a different fateful act: What if Chamberlain had stood up to Hitler? How would the war have unfolded and changed our world?

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 this extraordinary World War II alternate history, master storyteller Harry Turtledove begins with a big switch: what if Neville Chamberlain, instead of appeasing Hitler, had stood up to him in 1938? Enraged, Hitler reacts by lashing out at the West, promising his soldiers that they will reach Paris by the new year.

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 an extraordinary saga of nations locked in war, master storyteller Harry Turtledove tells the story of World War II, which begins over Czechoslovakia rather than Poland, eleven months earlier than it really came. Now comes the final installment in Turtledove's landmark World War II series. Hitler's Plan A was to win in a hurry, striking hard and deep into France. There was no Plan B. Now the war grinds on, and countries have been forced into strange alliances.

1945: Russian troops have entered Berlin, and are engaged in a violent orgy of robbery, rape, and revenge! Wehrmacht officer Hasso Pemsel, a career soldier on the losing end of the greatest war in history, flees from a sniper's bullet, finding himself hurled into a mysterious, fantastic world of wizards, dragons, and unicorns!

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.

In the 21st century, Germany's Third Reich continues to thrive after its victory in World War II - keeping most of Europe and North America under its heel. But within the heart of the Nazi regime, a secret lives. Under a perfect Aryan facade, Jews survive - living their lives, raising their families, and fearing discovery.... 

“I have sensed a disturbance in the Force.” Ominous words under any circumstances, but all the more so when uttered by Emperor Palpatine. On Batuu, at the edges of the Unknown Regions, a threat to the Empire is taking root - its existence little more than a glimmer, its consequences as yet unknowable. But it is troubling enough to the Imperial leader to warrant investigation by his most powerful agents: ruthless enforcer Lord Darth Vader and brilliant strategist Grand Admiral Thrawn.
