I don’t read a lot of page turners. I often find myself unable to put a book down—but they’re not the kinds of books that would keep most people glued to their chairs. Still, I recently found myself reading a book so compelling that I couldn’t turn away. Bad Blood: Secrets and Lies in a Silicon Valley Startup by John Carreyrou details the rise and fall of Theranos. If you aren’t familiar with the Theranos story, here’s the short version: the company promised to quickly give you a complete picture of your health using only a small amount of blood. Elizabeth Holmes founded it when she was just 19 years old, and both she and Theranos quickly became the darlings of Silicon Valley. She gave massively popular TED talks and appeared on the covers of Forbes and Fortune. By 2013, Theranos was valued at nearly $10 billion and even partnered with Walgreens to put their blood tests in stores around the country. The problem? Their technology never worked. It never came close to working. But Holmes was so good at selling her vision that she wasn’t stopped until after real patients were using the company’s “tests” to make decisions about their health. She and her former business partner are now facing potential jail time on fraud charges, and Theranos officially shut down in August. The public didn’t know about Theranos’ deception until Carreyrou broke the story as a reporter at the Wall Street Journal. Because he was so integral to the company’s demise, Bad Blood offers a remarkable inside look.
