Bad blood
secrets and lies in a Silicon Valley startup
In 2015, Theranos founder and CEO Elizabeth Holmes was widely seen as the female Steve Jobs: a brilliant Stanford dropout whose startup "unicorn" promised to revolutionize the medical industry with a machine that would make blood testing significantly faster and easier. Backed by investors such as Larry Ellison and Tim Draper, Theranos sold shares in a fund-raising round that valued the company at more than $9 billion, putting Holmes's worth at an estimated $4.5 billion. There was just one problem: the technology didn't work. For years, Holmes had been misleading investors and retail partners such as Safeway and Walgreens, hiding the fact that her technology was flawed and had serious limitations. Meanwhile, Holmes and her partner, Sunny Balwani, fostered a mercurial and highly secretive workplace environment in which Theranos employees routinely saw their colleagues fired for raising red flags. Their deception would lead to nearly one million false test results, some of which seriously jeopardized the health of patients. When John Carreyrou, a reporter at the Wall Street Journal, got a tip and started asking questions, both Carreyrou and the Journal were threatened with lawsuits, as were many of Carreyrou's sources. Undaunted, the newspaper ran the first of dozens of Theranos articles in late 2015. By early 2017, the company's value was zero, and in March 2018, the SEC charged Holmes with perpetrating "an elaborate, years-long fraud." Here is the gripping story of the biggest corporate fraud since Enron, a cautionary tale set amid the bold promises and gold-rush frenzy of Silicon Valley.
Beyond its central premise, the book can be read through the connected lenses of Nonfiction, Fiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book
This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.
Best when you want to settle into a longer reading experience.
Begin with its place in Nonfiction, then notice where the book resists that label.
Read for connection, not completion.
Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.
Three questions to carry with you
- Whose perspective organizes the story, and whose perspective remains outside it?
- Which sources or lived experiences carry the author’s central argument?
- How does the book change the way you understand its larger subject?
