Sarah Wynn-Williams joined Facebook believing the company could change things for the better. Instead, what she encountered over seven years was so shocking that Meta obtained a legal order to silence her.

Now you can read her award-winning story. Candid and entertaining, Wynn-Williams' account pulls back the curtain on Mark Zuckerberg, Sheryl Sandberg and the global elite. She exposes the true cost of Silicon Valley's ambition, from outrageous schemes cooked up on private jets to the alarming consequences of Facebook's aggressive pursuit of global dominance.

Careless People is an ordinary woman's gripping and darkly funny memoir that will forever change how you view the technology that runs our lives - and the unchecked power of those who control it.

With a new foreword for paperback from Naomi Alderman.

Urgently necessary reading -- Elizabeth Day, author of The Party and Friendaholic
Well-written, funny, horrifying, and quite compelling. I was on the edge of my seat, turning pages as fast as I could and ended up reading the book in less than a day. I cackled. I gasped. I laughed.
