We learned all about Facebook president Sean Parker's scandalous departure from the company nrkbeta We just finished reading Fortune editor David Kirkpatrick's upcoming book The Facebook Effect.

It's a must-read.

The Facebook Effect is not a Gladwell-wannabe. It's a fast-paced, can't-put-it-down, story about Mark Zuckerberg and Facebook's founding.

The book is brilliantly-reported and full of details about how Facebook's biggest deals came together – and how some even bigger deals did not. It even features tales of sex, drugs and rock 'n' roll.

We consider ourselves pretty well-versed in Facebook and Facebook's early days and we learned a TON reading this book. Go buy it now.

Correction: An earlier version of this post said that Mark Zuckerberg took two bonuses during Facebook fundraising. This fact is not in corrected versions of The Facebook Effect, publisher Simon & Schuster tells us.
