Katherine Losse, who joined the social network giant back in 2005 and remained for five years has a deal for "The Boy Kings: A Journey into the Heart of the Social Network."
The Free Press, an imprint of Simon & Schuster, announced Tuesday that the book will come out June 26.
Losse will offer a first-hand account of "the vision, culture, and tactics of the hackers, venture capitalists, and Ivy League grads" who helped make Facebook a worldwide force.
Losse left Facebook in 2010 on "friendly terms," according to the Free Press.
At Facebook, she was a writer and researcher.
