Benzinga's Spencer Israel caught up with Scott Wapner, CNBC anchor and author of 'When The Wolves Bite: Two Billionaires, One Company, and an Epic Wall Street Battle'

When The Wolves Bite tells the story of the greatest (or at least, most public) feud in the history of Wall Street: how Carl Icahn and Bill Ackman collided over Herbalife, and bet billions of dollars in the process.

The book brings new details to light, such as how Herbalife paid for a secret psychoanalysis of Ackman, as well as Ackman's desperate attempts to get the government to shut down Herbalife.

As Wapner puts it, "I wrote this book because I lived it."
