Mark Zuckerberg, who just celebrated his 28th birthday on Monday, is the second youngest self-made billionaire in the world, but now also the youngest CEO of a Fortune 1000 company to go public. It is also expected by many that 2012 will be the year Facebook joins the Fortune 500 list.

The news here is that Mark is about to join the list of the youngest CEO’s running Fortune 500 companies in the United States. Remember, the Facebook IPO officially starts trading on Friday, but you may have heard, on Monday, demand outweighed available shares and the underwriters of the deal approved another 50.6 million shares to be offered. Facebook also adjusted the price range from the originally planned $28 to $35 to $34 to $38.

So, as you can imagine, these are exciting times to be a part of the Facebook team, especially if you are a large shareholder, like Zuckerberg himself. But, it wasn’t so long ago that nobody knew what Facebook was and that social networking actually meant going out and meeting people.

Katherine Losse was an early employee at Facebook and back in 2005 she joined the team of Ivy League grads who made the social network a reality. She spent five years with that group building Facebook from he ground up. Now she has signed a deal with the Free Press, an imprint of Simon & Schuster.

On June 26th they will release a book called, “The Boy Kings: A Journey into the Heart of the Social Network”. Losse, who left Facebook on friendly terms, served as a researcher and writer at the social networking site. The book is her first hand account of how Facebook grew from just an idea to the networking empire we know today.

So if you want to learn more about Mark Zuckerberg and the multi-billion dollar company we know today, take a look at this book and discover what it was like watching the company and the people evolve into what we recognize as social networking today.
