Careless People

Careless People is a single memoir, and it is the account of a former insider who joined Facebook believing it could do real good in the world. Sarah Wynn-Williams, a New Zealand diplomat, talked her way into the company and rose to lead its global public policy work. The book describes those years from the centre of power, including private jets, summits with heads of state, and the company's leaders, Mark Zuckerberg and Sheryl Sandberg among them, as she saw them up close.

The title borrows Fitzgerald's phrase from The Great Gatsby. The publisher describes the book as shocking and darkly funny, and the shop's reading is that it is written by someone who stayed long enough to see how idealism can turn sour. It is a bestselling memoir for anyone who uses social media and has wondered who is really steering it.
