The most critical months of the 20th century.
World in the Balance: The Perilous Months of June-October 1940
The "smart money" was on Britain to collapse within weeks of battling Germany after the fall of France, or to make an accommodating peace. It didn't happen and there's more to the story than Spitfires. This book tells those stories.
Steel: From Mine to Mill, the Metal that Made America
Steel made America, and America's mills won two world wars. I traveled to open pit iron mines in Minnesota, rode an ore boat from Duluth to Cleveland then "followed the iron" into blast furnaces, steelmaking furnaces, and rolling mills for a unique look at what steel is, how it is made, and how it has affected history. This book tells the story of humanity's most important metal from the Iron Age to the Steel Age, and takes readers into the mills where steel is born of fire and pressure.
