If you read Fall of Giants, you must read the sequel Winter of the World. There's not a lot to add to the description of the first book below, except the setting this time is World War II instead of World War I, and the story involves the next generation of characters from the first book. Follett is just an exceptional historian, and you cannot read these books without learning things about history that you didn't know before. I was especially intrigued with the view of WWII from Russia's viewpoint, as that is not something that we cover extensively in my history classes. I'll be waiting for the next installment in another year or two.
