"[A] chilling, third-person narrative of how Holmes came up with a fantastic idea that made her, for a while, the most successful woman entrepreneur in Silicon valley.... Prizewinning Wall Street Journal reporter John Carreyrou tells [this story] virtually to perfection.... [His] description of Holmes as a manic leader who turned coolly hostile when challenged is ripe material for a psychologist.... His recounting of his efforts to track down sources - many of whom were being intimidated by Theranos’s bullying lawyer, David Boies - reads like a West Coast version of All the President's Men." (Roger Lowenstein, The New York Times Book Review) 

"Carreyrou blends lucid descriptions of Theranos’s technology and its failures with a vivid portrait of its toxic culture and its supporters’ delusional boosterism. The result is a bracing cautionary tale about visionary entrepreneurship gone very wrong." (Publishers Weekly)

"Eye-opening.... A vivid, cinematic portrayal of serpentine Silicon Valley corruption.... A deep investigative report on the sensationalistic downfall of multibillion-dollar Silicon Valley biotech startup Theranos. Basing his findings on hundreds of interviews with people inside and outside the company, two-time Pulitzer Prize-winning Wall Street Journal reporter Carreyrou rigorously examines the seamy details behind the demise of Theranos and its creator, Elizabeth Holmes.... [Carreyrou] brilliantly captures the interpersonal melodrama, hidden agendas, gross misrepresentations, nepotism, and a host of delusions and lies that further fractured the company’s reputation and halted its rise." (Kirkus) 

"Crime thriller authors have nothing on Carreyrou's exquisite sense of suspenseful pacing and multifaceted character development in this riveting, read-in-one-sitting tour de force.... Carreyrou's commitment to unraveling Holmes' crimes was literally of life-saving value." (Booklist, starred review)
