"Bad Blood" by John Carreyrou is an investigative exposé that delves into the shocking rise and fall of Theranos, a Silicon Valley biotech company. Founded by Elizabeth Holmes, Theranos promised revolutionary blood-testing technology that could run comprehensive tests using just a few drops of blood. The book chronicles the company's meteoric rise to a $9 billion valuation, Holmes' charismatic leadership, and the cult-like corporate culture she fostered. However, Carreyrou reveals how Theranos' technology was deeply flawed and its practices fraudulent. Through meticulous research and whistleblower accounts, the book unravels the deception and ethical breaches that led to the company's eventual downfall and legal scrutiny. "Bad Blood" serves as a cautionary tale about ambition, innovation, and the consequences of unchecked power in the tech industry.
