General Stanley McChrystal, commander of international and US forces in Afghanistan, was living large, with staff calling him a rock star.

Journalist Michael Hastings of Rolling Stone looked on as McChrystal and his staff let off steam, partying and openly bashing the Obama administration. When Hastings' piece appeared a few months later, it set off a political firestorm: McChrystal was ordered to Washington, where he was unceremoniously fired.

Hastings gives us a shocking behind-the-scenes portrait of Allied military commanders, their high-stakes manoeuvres and often bitter bureaucratic infighting.
