John Carreyrou's 'Bad Blood' provides an explosive and detailed account of the scandal that rocked Silicon Valley and captured global attention. The book chronicles the dizzying ascent and the calamitous fall of Theranos, a biotech startup once valued at billions, founded by Elizabeth Holmes—a prodigy poised to revolutionize health care with innovative blood testing technology. However, beneath the veneer of success, Theranos's technology was flawed, yielding inaccurate results that endangered lives and misled investors and patients. Carreyrou's investigative journalism exposes the deception and challenges faced when confronting the powerful, ultimately revealing the perils of blind belief in the cult of personality and the idea of an infallible entrepreneur.
