A New York Times reporter’s “vivid” account of the dramatic rise of Bitcoin and how it has led to untold riches for some—and prison terms for others (Financial Times). Shortlisted for the Financial Times and McKinsey Business Book of the Year A New York Times Book Review Editor’s Choice The notion of a new currency, maintained by the computers of users around the world, has been the butt of many jokes, but that has not stopped it from growing into a technology worth billions of dollars, supported by the hordes of followers who have come to view it as the most important new idea since the creation of the Internet. Believers from Beijing to Buenos Aires see the potential for a financial system free from banks and governments. More than just a tech industry fad, Bitcoin has threatened to decentralize some of society’s most basic institutions. An unusual tale of group invention, Digital Gold charts the rise of the Bitcoin technology through the eyes of the movement’s colorful central characters, including an Argentinian millionaire, a Chinese entrepreneur, Tyler and Cameron Winklevoss, and Bitcoin’s elusive creator, Satoshi Nakamoto. “Engrossing.” —Library Journal “An elegant, thrilling tour-de-force. . . .The fast-paced action never stops.” —William D. Cohan, New York Times–bestselling author of Power Failure

Ken Liu writes about a virtual currency that hijacks our empathy; Elizabeth Bear shows us a smart home tricked into kidnapping its owner; Clifford V. Johnson presents, in a graphic novella, the story of a computer scientist seeing a new side of the AIs she has invented; and J. M. Ledgard describes a 28,000-year-old AI who meditates on the nature of loneliness. We encounter metal-melting viruses, vegetable-based heart transplants, search-and-rescue drones, and semi-automated sailing ships.

In his celebrated account of the origins of American unity, John Adams described July 1776 as the moment when thirteen clocks managed to strike at the same time. So how did these American colonies overcome long odds to create a durable union capable of declaring independence from Britain? In this powerful new history of the fifteen tense months that culminated in the Declaration of Independence, Robert G. Parkinson provides a troubling answer: racial fear. Tracing the circulation of information in the colonial news systems that linked patriot leaders and average colonists, Parkinson reveals how the system's participants constructed a compelling drama featuring virtuous men who suddenly found themselves threatened by ruthless Indians and defiant slaves acting on behalf of the king. Parkinson argues that patriot leaders used racial prejudices to persuade Americans to declare independence. Between the Revolutionary War's start at Lexington and the Declaration, they broadcast any news they could find about Native Americans, enslaved Blacks, and Hessian mercenaries working with their British enemies. American independence thus owed less to the love of liberty than to the exploitation of colonial fears about race. Thirteen Clocks offers an accessible history of the Revolution that uncovers the uncomfortable origins of the republic even as it speaks to our own moment.
