What to expect

‘I couldn’t put down this thriller’ – Bill Gates

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.

Critics Review

  • I couldn’t put down this thriller with a tragic ending . . . a book so compelling that I couldn’t turn away . . . This book has everything: elaborate scams, corporate intrigue, magazine cover stories, ruined family relationships, and the demise of a company once valued at nearly $10 billion

    Bill Gates, '5 books I loved in 2018'
  • A dazzling story of deception in Silicon Valley . . . You will not be able to put this book down.

    Washington Post
  • Carreyrou tells the story virtually to perfection . . . Bad Blood reads like a West Coast version of All the President’s Men.

    New York Times Book Review
  • Riveting . . . a blistering critique of Silicon Valley . . . 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

    Financial Times
  • If you’re looking for an engaging non-fiction read, look no further than Bad Blood . . . a pacy, compelling narrative about white-collar crime that’s as incredible as any work of fiction.

    Irish Times
  • In this Silicon Valley drama, he opens his reporter’s notebook to deliver a tale of corporate fraud and legal browbeating that reads like a crime thriller.
