Elizabeth Holmes wanted to be the next Steve Jobs. But John Carreyrou’s reporting in Bad Blood shows that her Silicon Valley start-up, Theranos, turned out to be an enormous fraud, and we burned through the book in 2 days. Holmes started Theranos when she was 19, having dropped out of Stanford University, and she claimed to have devised blood tests that only required very small amounts of blood at Theranos. She became the world’s youngest billionaire on the way to a federal indictment for defrauding investors.
