Bad Blood tells the true story of Theranos, a Silicon Valley startup that promised to revolutionize blood testing.

Founded by Elizabeth Holmes, the company claimed it could run hundreds of tests from just a few drops of blood.

Holmes built a powerful image as a visionary entrepreneur and attracted huge investments from wealthy and influential backers.

Behind the scenes, however, Theranos’s technology was deeply flawed and often failed to deliver accurate results.

Employees who questioned the company’s methods faced secrecy, intimidation, and pressure to stay silent.

John Carreyrou shows how Holmes and her partner, Sunny Balwani, misled investors, doctors, patients, and the public.

The book also reveals how Theranos used hype, media attention, and famous board members to hide the truth.

Investigative journalism played a key role in exposing the deception and bringing the scandal into public view.

As the fraud unraveled, Theranos collapsed, and Holmes became a symbol of ambition, deception, and startup culture gone wrong.

Overall, the book is a gripping warning about unchecked power, blind trust in innovation, and the dangers of fake success.
