Second Contact (Colonization, Book 1)
In the extraordinary Worldwar tetralogy, set against the backdrop of the 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.From the Paperback edition.
Beyond its central premise, the book can be read through the connected lenses of Science Fiction, Nonfiction, Fiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.
Best when you want to settle into a longer reading experience.
Begin with its place in Science Fiction, then notice where the book resists that label.
Read for connection, not completion.
Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.
Three questions to carry with you
- Which familiar part of life becomes easier to see through this imagined world?
- What rules shape the world, and who benefits from them?
- Where does wonder, fear, or possibility change a character’s choices?
