“[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 “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

“Harry Turtledove [is] probably the best-known practitioner of alternate history working today.”— American Heritage The year is 1915, and the world is convulsing. Though the Confederacy has defeated its northern enemy twice, this time the United States has allied with the Kaiser. In the South, the freed slaves, fueled by Marxist rhetoric and the bitterness of a racist nation, take up the weapons of the Red rebellion. Despite these advantages, the United States remains pinned between Canada and the Confederate States of America, so the bloody conflict continues and grows. Both presidents—Theodore Roosevelt of the Union and staunch Confederate Woodrow Wilson—are stubbornly determined to lead their nations to victory, at any cost. . .

In a parallel-world 21st-century San Francisco where the Kaiser's Germany won World War One and went on to dominate the world, Paul Gomes and his father Lawrence are secret agents for our timeline, posing as traders from a foreign land. They run a storefront shop called Curious Notions, selling what is in our world routine consumer technology-record players, radios, cassette decks--all of which is better than anything in this world, but only by a bit. Their real job is to obtain raw materials for our timeline. Just as importantly, they must guard the secret of Crosstime Traffic--for of the millions of parallel timelines, this is one of the few advanced enough to use that secret against us. Now, however, the German occupation police are harrassing them. They want to know where they're getting their mysterious goods. Under pressure, Paul and Lawrence hint that their supplies comes from San Francisco's Chinese...setting in motion a chain of intrigues that will put the entire enterprise of Crosstime Traffic at deadly risk.
