With esteemed historian David Frye as our raconteur-guide in Walls, which Publishers Weekly praises as "informative, relevant, and thought-provoking," we journey back to a time before barriers of brick and stone even existed--to an era in which nomadic tribes vied for scarce resources, and each man was bred to a life of struggle. Ultimately, those same men would create edifices of mud, brick, and stone, and with them effectively divide humanity: on one side were those the walls protected; on the other, those the walls kept out.

The stars of this narrative are the walls themselves--rising up in places as ancient and exotic as Mesopotamia, Babylon, Greece, China, Rome, Mongolia, Afghanistan, the lower Mississippi, and even Central America. As we journey across time and place, we discover a hidden, thousand-mile-long wall in Asia's steppes; learn of bizarre Spartan rituals; watch Mongol chieftains lead their miles-long hordes; witness the epic siege of Constantinople; chill at the fate of French explorers; marvel at the folly of the Maginot Line; tense at the gathering crisis in Cold War Berlin; gape at Hollywood's gated royalty; and contemplate the wall mania of our own era.

Hailed by Kirkus Reviews as "provocative, well-written, and--with walls rising everywhere on the planet--timely," Walls gradually reveals the startling ways that barriers have affected our psyches. The questions this book summons are both intriguing and profound: Did walls make civilization possible? And can we live without them? Find out in this masterpiece of historical recovery and preeminent storytelling.
