Second Contact

Book 1

“[A] tour de force of speculative historical fiction. Highly recommended.”—Library Journal

In the extraordinary Worldwar tetralogy, set against the backdrop of 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.

Praise for Second Contact

Down to Earth

by Harry Turtledove

Published 2 January 2001
“The leading author of alternate history.”—USA Today

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 . . .

Aftershocks

by Harry Turtledove

Published 6 December 2001

Humanity is still locked in a battle for supremacy with the conquering alien invaders, the Race. The German Reich has finally been subdued and the Race believe it only to be a matter of time before the rest of the planet follows suit. However, they underestimate humanity's desire for freedom and the lengths they will go to gain it.
With America and Russia holding the alien invaders off in a technological standoff, the disorganised red armies of Mao Tse-tung's revolutionaries causing havoc and the ever-increasing dependence of the Race on the addictive substance ginger, the Empire realises that the colonisation of Earth may only be achieved through its total destruction.
