NATIONAL BESTSELLER • "More impressive than all but a few novels published so far this decade . . . a wheeling meditation on the wired life, on privacy, on what being human in the age of binary code might mean . . . [Joshua] Cohen, all of thirty-four, emerges as a major American writer."-The New York Times

NAMED ONE OF THE TEN BEST BOOKS OF THE YEAR BY VULTURE AND ONE OF THE BEST BOOKS OF THE YEAR BY NPR AND THE WALL STREET JOURNAL

"Book of Numbers . . . is shatteringly powerful. I cannot think of anything by anyone in [Cohen's] generation that is so frighteningly relevant and composed with such continuous eloquence. There are moments in it that seem to transcend our impasse."-Harold Bloom

The enigmatic billionaire founder of Tetration, the world's most powerful tech company, hires a failed novelist, Josh Cohen, to ghostwrite his memoirs. The mogul, known as Principal, brings Josh behind the digital veil, tracing the rise of Tetration, which started in the earliest days of the Internet by revolutionizing the search engine before venturing into smartphones, computers, and the surveillance of American citizens. Principal takes Josh on a mind-bending world tour from Palo Alto to Dubai and beyond, initiating him into the secret pretext of the autobiography project and the life-or-death stakes that surround its publication.

Insider tech exposé, leaked memoir-in-progress, international thriller, family drama, sex comedy, and biblical allegory, Book of Numbers renders the full range of modern experience both online and off. Embodying the Internet in its language, it finds the humanity underlying the virtual.

Featuring one of the most unforgettable characters in contemporary fiction, Book of Numbers is an epic of the digital age, a triumph of a new generation of writers, and one of those rare books that renew the idea of what a novel can do.
