Second Contact: Harry Turtledove

Book V of Worldwar; Book I of Colonisation. Set in the alternate history of the volatile 1960s, when the space race is in its infancy and humanity must face its greatest challenge: alien colonisation of planet Earth.Yet even in the shadow of this inexorable foe, the United States, the Soviet Union, and Nazi Germany are unable to cease 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. Cover art by Fred Gambino.
