In the depths of the Great War, with millions dead and no imaginable end to the conflict, societies around the world began to buckle. The heart of the financial system shifted from London to New York. The infinite demands for men and materiel reached into countries far from the front. The strain of the war ravaged all economic and political assumptions, bringing unheard-of changes in the social and industrial order.

When the British voted to leave the European Union in 2016, the country's future was thrown into doubt. So, too, was its past. The story of British history is no longer a triumphalist narrative of expanding global empire, nor one of ever-closer integration with Europe. What is it now? In Island Stories, historian David Reynolds offers a multi-faceted new account of the last millennium to make sense of Britain's turbulent present.

In the heart of North America, the Missouri, Ohio, and Mississippi rivers come together, uniting waters from west, north, and east on a journey to the south. This is the region that Stephen Aron calls the American Confluence. Aron's innovative book examines the history of that region - a home to the Osage, a colony exploited by the French, a new frontier explored by Lewis and Clark - and focuses on the region's transition from a place of overlapping borderlands to one of oppositional border states.

We are familiar with maps that outline all 50 states. And we are also familiar with the idea that the United States is an "empire", exercising power around the world. But what about the actual territories - the islands, atolls, and archipelagos - this country has governed and inhabited? In How to Hide an Empire, author Daniel Immerwahr tells the fascinating story of the United States outside the United States. In crackling, fast-paced prose, he reveals forgotten episodes that cast American history in a new light.

The Second World Wars examines how combat unfolded in the air, at sea, and on land to show how distinct conflicts among disparate combatants coalesced into one interconnected global war. Drawing on 3,000 years of military history, Victor Davis Hanson argues that despite its novel industrial barbarity, neither the war's origins nor its geography were unusual. Nor was its ultimate outcome surprising. The Axis powers were well prepared to win limited border conflicts, but once they blundered into global war, they had no hope of victory.
