Bad Blood: Secrets and Lies in a Silicon Valley Startup

Bad Blood: Secrets and Lies in a Silicon Valley Startup is a nonfiction book by journalist John Carreyrou, released May 21, 2018. It covers the rise and fall of Theranos, the multibillion-dollar biotech startup headed by Elizabeth Holmes. The book received critical acclaim, winning the 2018 Financial Times and McKinsey Business Book of the Year Award.

In 2021, a film adaptation was announced, to star Jennifer Lawrence, to be written by Vanessa Taylor and to be directed by Adam McKay. However, after seeing Amanda Seyfried's critically acclaimed performance playing Holmes in the limited series The Dropout, Lawrence exited the project.
