Among the four books already published about security contractors in Iraq, this is for sure one of the best, if not the best. You'll get a picture of the atmosphere you sense in Baghdad, the mayhem and the comradeship. It's a well written book, I recommend it even for the final considerations about US foreign policy especially in Iraq. James Ashcroft tells you what Time, even criticizing the US foreign policy in Iraq, was not able to say: Bremer's awful mistakes, the gung ho people and the desk generals who ponder things the US way.
Buy this book and you'll not regret the money you spent.
