Bad Blood: Secrets and Lies in a Silicon Valley Startup by John Carreyrou is the strongest book-length starting point for understanding the Theranos scandal. It traces the company’s rise and collapse, examines its blood-testing claims and leadership, and follows the employees and investigative reporting that brought those claims under scrutiny. The updated publisher listing also describes an afterword covering Elizabeth Holmes’s trial and sentencing.

| Bad Blood: Secrets and Lies in a Silicon Valley Startup by John Carreyrou | Readers looking for a reported narrative of Theranos’s rise, exposure and collapse | Draws on extensive interviews; the publisher’s Canada listing notes an afterword on Holmes’s trial and sentencing | November 2026 |
What is the best book about Theranos?
For a single, substantial account, start with Carreyrou’s Bad Blood. The publisher’s description and the book’s coverage support it as the clearest comprehensive book-length investigation of Theranos; they do not establish another Theranos title as an equally documented alternative.
Carreyrou was a Wall Street Journal reporter, and the publisher identifies him as a two-time Pulitzer Prize winner. The book recounts how Theranos attracted attention and investment with promises of revolutionary blood testing, then tracks the reporting and whistleblowing that challenged the company’s claims. It also explores Holmes’s public image, the company’s internal culture and leadership, and the role Silicon Valley’s appetite for bold technology promises played in its rise.
That combination makes Bad Blood useful beyond the basic question of what happened. It connects the company’s claims to the people and decisions behind them, and shows how employees, sources and journalists helped bring the story into public view. The account is an investigative narrative, not a technical manual for evaluating laboratory tests.

What does Bad Blood cover?
The book follows Theranos from its promise of transforming blood testing through the scrutiny that exposed the gap between the company’s claims and its operations, and on to its collapse. Its central subjects are not only Holmes and the technology claims but also the company’s culture, employees who raised concerns, and the reporting that investigated those concerns.
- The company’s rise: how Theranos presented itself as a breakthrough blood-testing company and drew extraordinary attention and investment.
- Holmes’s image and Silicon Valley’s expectations: how public presentation and faith in ambitious technology promises shaped the company’s ascent.
- The scrutiny: how employees, sources and investigative journalism challenged Theranos’s claims.
- The collapse: how leadership relationships, internal culture and alleged misrepresentations contributed to the company’s downfall.
The publisher describes the book as based on hundreds of interviews. A later edition listing adds a new afterword about Holmes’s trial and sentencing, extending the narrative beyond the company’s collapse.
Does Bad Blood cover Elizabeth Holmes’s trial?
The publisher’s Canada listing for the book says its edition includes a new afterword covering Holmes’s trial and sentencing. If that later legal chapter matters to you, check the edition description rather than assuming every copy has the same material.

Is Bad Blood worth reading after watching The Dropout?
Yes, if you want an investigative book-length account rather than another screen presentation. The book’s distinctive value is its reported reconstruction of the company’s claims, the internal challenges to those claims, and the journalism that exposed them. The publisher’s interview-based description and the book’s focus on whistleblowing offer a different way to understand how the scandal unfolded.
The book and a screen or audio account are different formats, so one should not be treated as a substitute for the other. If your interest is specifically in the trial and sentencing, look for an edition whose listing confirms that it includes the afterword.

Which edition or format should you choose?
Choose by coverage and the format you prefer, not by an assumed difference in the core story. The Canadian publisher listing explicitly notes the afterword on Holmes’s trial and sentencing. Format availability—including print, ebook and audiobook options—varies by market and retailer, and no complete, current inventory or prices are confirmed here.
Before buying, check the seller’s edition description for the afterword and format, and compare the publication details with the publisher’s listing. Apple Books has a listing for the title, while WorldCat provides a catalog record for the print book. These records can help identify the work, but retailer availability and pricing may change.
How should you use the book to understand the scandal?
Read it as a reported account of how a company’s promises, leadership and internal practices came under scrutiny—not as a verdict on every question about blood testing or corporate fraud. The narrative is particularly suited to readers who want to follow the people and reporting behind the exposure.

For a focused reading, pay attention to the sequence between public claims, internal concerns and outside investigation. That chronology helps clarify why employees’ accounts and investigative reporting mattered, and how the company’s image and technology promises shaped reactions to criticism. The afterword, where included, adds the later trial and sentencing to the account.
How we chose this recommendation
The recommendation is based on the scope described by the publisher, catalog and published coverage: direct focus on Theranos, a substantial investigative narrative, extensive interviews, and an edition listing that addresses Holmes’s trial and sentencing. The publisher’s description and published coverage identify Bad Blood as the strongest comprehensive book-length investigation, but do not provide comparable evidence for ranking other books about Theranos. Documentaries, podcasts and dramatizations may be useful in other formats, but they are not books and are not presented here as book alternatives.
