The Power of One: How I Found the Strength to Tell the Truth and Why I Blew the Whistle on Facebook
Haugen's 2023 memoir traces the personal history she says shaped her decision to leak internal Facebook documents and testify publicly: the loss of a close friend to online misinformation-fueled radicalization, a serious illness that temporarily left her unable to work or walk, and her path through the tech industry into Facebook's Civic Integrity team. The book recounts how she copied roughly 22,000 pages of internal material before leaving the company in 2021 and walks through her subsequent congressional testimony and international advocacy. It is a first-person account rather than new data or analysis; TechKids Foundation cites it as the fullest public record of her own stated motivations and of how she characterizes what Facebook's internal research found.
