Former Fortune magazine technology reporter David Kirkpatrick tracks the meteoric rise of Facebook from dorm room novelty to a social networking website with 500 million users.

Kirkpatrick had the full cooperation of Facebook’s key executives in researching his book about the company and its impact on people’s lives. He chronicles its successes and missteps and gives readers a complete assessment of founder and CEO Mark Zuckerberg, the central figure in the company’s remarkable ascent.

The book will be available for sale.
