Frances Haugen, the former Facebook employee and whistleblower who leaked company documents to the Wall Street Journal, is writing a memoir, the Associated Press reports.

Little, Brown will publish Haugen’s book, as yet untitled and with no confirmed release date.

“During my time at Facebook I realized a devastating truth: Almost nobody outside of Facebook knows what happens inside of Facebook,” Haugen said in a statement. “They operate in the dark.”

Haugen, a former Facebook product manager, shared internal company documents with the Wall Street Journal, which used them as the basis for a series of articles known as the “Facebook Files.” The reports claimed that the company failed to take action against hate-filled posts and didn’t address concerns that Instagram, its photo-sharing app, was harmful to teenagers.

In October, Haugen revealed that she was behind the leaks. She testified before the U.S. Senate shortly thereafter.

Haugen shared the news of her book on Twitter, writing, “A book is a perfect forum to explore the nuance and complexity of the problems Facebook faces, and I’m very excited about this collaboration with [Little, Brown and editor Vanessa Mobley]. As I learned from my mother, ‘every human being deserves the dignity of the truth.’”
