NATIONAL BESTSELLER • The gripping story of Elizabeth Holmes and T heranos — one of the biggest corporate frauds in history—a tale of ambition and hubris set amid the bold promises of Silicon Valley, rigorously reported by the prize-winning journalist. With a new Afterword covering her trial and sentencing, bringing the story to a close. “Chilling ... Reads like a thriller ... Carreyrou tells [the Theranos story] virtually to perfection.” — The New York Times Book Review In 2014, Theranos founder and CEO Elizabeth Holmes was widely seen as the next Steve Jobs: a brilliant Stanford dropout whose startup “unicorn” promised to revolutionize the medical industry with its breakthrough device, which performed the whole range of laboratory tests from a single drop of blood. Backed by investors such as Larry Ellison and Tim Draper, Theranos sold shares in a fundraising round that valued the company at more than $9 billion, putting Holmes’s worth at an estimated $4.5 billion. There was just one problem: The technology didn’t work. Erroneous results put patients in danger, leading to misdiagnoses and unnecessary treatments. All the while, Holmes and her partner, Sunny Balwani, worked to silence anyone who voiced misgivings—from journalists to their own employees. " Bad Blood is the real be-all end-all of Theranos information…. Bad Blood is wild, and more happens on one page than in many other entire books." —Margaret Lyons, The New York Times "You will not want to put this riveting, masterfully reported book down. No matter how bad you think the Theranos story was, you'll learn that the reality was actually far worse." —Bethany McLean, bestselling coauthor of The Smartest Guys in the Room and All the Devils Are Here "Chilling... Carreyrou tells [this story] virtually to perfection… Reads like a West Coast version of All the President's Men. " —Roger Lowenstein, The New York Times Book Review "The definitive account of Theranos’s downfall, detailing its motley crew of executives, legal knife fights, dramatic PR stunts, and skullduggery... Offers a lot for foreign-policy wonks... While Bad Blood is worth reading for its own merits—it’s a stunning feat of journalism that reads like a thriller—it also says a lot about Washington’s facile relationship with Silicon Valley. Most D.C. power brokers know next to nothing about science or technology but increasingly view Silicon Valley tech as a deus ex machina for some of the world’s most complicated challenges. Bad Blood offers a sobering warning of where that type of thinking can lead." —Robbie Gramer, Foreign Policy "A great and at times almost unbelievable story of scandalous fraud, surveillance, and legal intimidation at the highest levels of American corporate power. . . . The story of Theranos may be the biggest case of corporate fraud since Enron. But it’s also the story of how a lot of powerful men were fooled by a remarkably brazen liar." —Yashar Ali, New York Magazine "Even if you didn’t follow the story of charismatic Theranos founder Elizabeth Holmes (and the ensuing trainwreck) in the news, you will find yourself zipping through a book that proves once again that fact is stranger than fiction. A stunning look into a high-tech hoodwinking; like a high-speed car chase in a book." —The New York Post's "28 Most Unforgettable Books of 2018" "In Bad Blood, acclaimed investigative journalist John Carreyrou, who broke the story in 2015, presents comprehensive evidence of the fraud perpetrated by Theranos chief executive Elizabeth Holmes... He unveils many dark secrets of Theranos that have not previously been laid bare…  The combination of these brave whistle-blowers, and a tenacious journalist who interviewed 150 people (including 60 former employees) makes for a veritable page-turner." —Eric Topol, Nature "Engrossing… Bad Blood boasts movie-scene detail… Theranos, Carreyrou writes, was a revolving door, as Holmes and Balwani fired anyone who voiced even tentative doubts… What’s frightening is how easy it is to imagine a different outcome, one in which the company’s blood-testing devices continued to proliferate. That the story played out as it did is a testament to the many individuals who spoke up, at great personal risk." —Jennifer Couzin-Frankel, Science "In exposing the fudged numbers, boardroom battles and sickening sums of money tossed Theranos’ way, Bad Blood succeeds in highlighting Silicon Valley’s paradoxical blind spot. Insular corporate culture and benevolent media coverage have allowed a monster to grow in the Valley—one that gambles not just with our smart phones or our democracy, but with people’s lives. 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." —B.
