An award-winning investigative nonfiction book by John Carreyrou that chronicles one of the biggest corporate frauds in modern history—the spectacular rise and collapse of Theranos.

The book follows the meteoric ascent of Elizabeth Holmes, a charismatic young entrepreneur who dropped out of Stanford University and founded Theranos with the promise of revolutionizing blood testing. Holmes claimed that her company had developed technology capable of performing hundreds of medical tests using just a few drops of blood. Her vision attracted billions of dollars in investment, partnerships with major pharmacy chains, and support from influential politicians, military leaders, and business executives.

As Theranos grew into a Silicon Valley sensation valued at over $9 billion, investigative journalist John Carreyrou began uncovering disturbing evidence that the company's technology did not work as advertised. Drawing on confidential documents, interviews with whistleblowers, former employees, investors, and regulators, he reveals a culture of secrecy, intimidation, deception, and relentless pressure inside the company.

The narrative follows the painstaking investigation that exposed falsified demonstrations, inaccurate blood-test results, and deliberate efforts to mislead investors, doctors, and patients. It also highlights the courage of employees who risked their careers to reveal the truth and the challenges faced by journalists pursuing powerful corporations.

Fast-paced and meticulously researched, Bad Blood reads like a corporate thriller while exploring themes of ambition, ethics, innovation, whistleblowing, corporate governance, and the dangers of blind faith in charismatic founders.
