This is a story that starts off close and goes very big. The initial part of the story might sound familiar at first: it is about a platoon of mostly 19-year-old boys sent to Afghanistan, and an experience that ends abruptly in catastrophe. Their part of the story folds into the next: inexorably linked to those soldiers and never comprehensively reported before is the US Department of Defense’s quest to build the world’s most powerful biometrics database, with the ability to identify, monitor, catalog, and police people all over the world.

The Sleepwalkers: How Europe Went to War in 1914 is historian Christopher Clark’s riveting account of the explosive beginnings of World War I. Drawing on new scholarship, Clark offers a fresh look at World War I, focusing not on the battles and atrocities of the war itself, but on the complex events and relationships that led a group of well-meaning leaders into brutal conflict.

They were called a generation without heroes. Then they were called upon to be heroes. Within hours of 9/11, America's war on terrorism fell to those like the 23 Marines of the First Recon Battalion, the first generation dispatched into open-ended combat since Vietnam.

Southern Afghanistan was slipping away. That was clear to then-Captain Rusty Bradley as he began his third tour of duty there in 2006. The Taliban and their allies were infiltrating everywhere, poised to reclaim Kandahar Province, their strategically vital onetime capital. To stop them, the NATO coalition launched Operation Medusa, the largest offensive in its history. The battlefield was the Panjwayi Valley, a densely packed warren of walled compounds that doubled neatly as enemy bunkers.

In November 1965, some 450 men of the First Battalion, Seventh Cavalry, under the command of Lt. Col. Hal Moore, were dropped by helicopter into a small clearing in the Ia Drang Valley. They were immediately surrounded by 2,000 North Vietnamese soldiers. Three days later, only two and a half miles away, a sister battalion was chopped to pieces. Together, these actions at the landing zones X-Ray and Albany constituted one of the most savage and significant battles of the Vietnam War. How these men persevered makes a vivid portrait of war at its most inspiring and devastating.

Discover the definitive history of DARPA, the Defense Advanced Research Project Agency, in this Pulitzer Prize finalist from the author of the New York Times best seller Area 51. No one has ever written the history of the Defense Department's most secret, most powerful, and most controversial military science R&D agency. In the first-ever history about the organization, New York Times best-selling author Annie Jacobsen draws on inside sources, exclusive interviews, private documents, and declassified memos to paint a picture of DARPA, or "the Pentagon's brain".

In the summer of 2006, David Fraser was the Canadian general in charge of NATO's Regional Command South, a territory spanning six Afghan provinces surrounding the Arghandab Valley. Birthplace of the Taliban decades earlier, this fertile region had since become Afghanistan's most deadly turf. It would soon turn deadlier still. Advised in the night by his intelligence officers that the Taliban had secretly amassed for a full-scale military assault, Fraser knew it would fall to him, his Canadians and their allies to avoid the wholesale slaughter of NATO troops.

In Disunited Nations, geopolitical strategist Peter Zeihan presents a series of counterintuitive arguments about the future of a world where trade agreements are coming apart and international institutions are losing their power. Germany will decline as the most powerful country in Europe, with France taking its place. Every country should prepare for the collapse of China, not North Korea. We are already seeing, as Zeihan predicts, a shift in outlook on the Middle East: it is no longer Iran that is the region’s most dangerous threat, but Saudi Arabia.

As a senior non-commissioned officer of Delta Force, the most elite and secretive special operations unit in the US military, Command Sergeant Major Tom Satterly fought some of this country's most fearsome enemies. Tom is a legend even among other Tier One special operators. Yet the enemy that cost him three marriages, and ruined his health physically and psychologically, existed in his brain. Told through Satterly's firsthand experiences, it also weaves in the reasons for his career-long battle against the most insidious enemy of all: post-traumatic stress.
