Winter of the World is the second novel in Ken Follett’s The Century Trilogy, continuing the story of five interconnected families through major 20th-century events. Set from the rise of Hitler in 1933 through the aftermath of World War II, the book covers the Spanish Civil War, WWII battles, espionage, and the development of nuclear weapons. Following nine main characters across several countries, Follett explores their personal struggles amid global upheaval, including anti-fascist resistance, love and loss, and ideological conflicts. The novel blends historical detail with suspenseful storytelling, though it has been noted for its selective focus on certain events like Pearl Harbor while only briefly addressing the Holocaust. Winter of the World sets the stage for the trilogy’s final volume, which explores the Cold War era.
