Bad Blood

A dazzling story of deception in Silicon Valley . . . It is a tale of heroic cupidity on a scale that made the very best and the very brightest look like the very, very foolish . . . You will not be able to put this book down. - Washington Post

Riveting . . . a blistering critique of Silicon Valley, a kind of nonfiction corollary to Dave Eggers's The Circle . . . compelling . . . [Carreyrou's] unmasking of Theranos is a tale of David and Goliath . . . The real heroes, though, are his sources: the young scientists who worked at the company and risked their reputations and careers by voicing their concerns. Were it not for their courage, Theranos might still be testing blood today - David Crow, Financial Times

Carreyrou tells the story virtually to perfection . . . Bad Blood reads like a West Coast version of All the President's Men. - New York Times

Gripping . . . Carreyrou presents the scientific, human, legal and social sides of the story in full . . . He unveils many dark secrets of Theranos that have not previously been laid bare. - Nature

Gripping . . . It is a parable, with all the usual, delicious ingredients of human folly: greed, pride, vanity, lust, anger. Above all, it is an analysis of the phenomenon of hype. - Daily Telegraph

Simply one of the best books about a startup ever. - Forbes

Bad Blood reveals a crucial truth: outside observers must act as the eyes, the ears and, most importantly, the voice of Silicon Valley's blind spot . . . It gambled not with our smart phones, our attention or our democracy, but with people's lives. - Paste
