“[A] tour de force of speculative historical fiction. Highly recommended.”—Library JournalIn 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“An exciting, often surprising, story that will not only delight his fans but will probably send newcomers back to the Worldwar saga.”—Publishers Weekly (starred review)“Outstanding entertainment.”—Booklist Read Less
