Winner of the Financial Times/McKinsey Business Book of the Year Award.

The shocking true story of the breathtaking rise and collapse of Theranos, the multibillion-dollar biotech startup founded by Elizabeth Holmes, written by the prize-winning journalist who first broke the story and pursued it to the end.

Seen as the female Steve Jobs, Theranos founder and CEO Elizabeth Holmes was a brilliant Stanford dropout whose startup ‘unicorn’ promised to revolutionize the medical industry with a machine that would make blood testing significantly faster and easier. Backed by wealthy investors, Theranos sold shares that valued the company at more than $9 billion.

There was just one problem: the technology didn’t work . . .

Despite threats of legal action, brave whistleblowers started to talk. They revealed a culture of intimidation and secrecy, technology that repeatedly failed, results sent to real patients that were incorrect but upon which life-changing medical decisions were being made, with devastating consequences.

The riveting story behind The Dropout, in Bad Blood, John Carreyrou investigates the biggest corporate fraud since Enron, a tale of ambition and scandal set amid the bold promises of Silicon Valley.
