Ex-special-forces-soldier-turned-bodyguard Charlotte "Charlie" Fox can never forget the men who put a brutal end to her military career. A long time ago, though, she vowed she wouldn't go looking for them - but now it seems she doesn't have a choice. Her boss Sean Meyer went missing in Iraq, where one of those men was working as a private security contractor. When that man's butchered body is discovered, Charlie fears that Sean may be pursuing a twisted vendetta on her behalf. Although Sean's intentions may be good, Charlie's "close protection" agency in New York needs the situation dealt with - fast and quiet. They send Charlie to the Middle East with very specific instructions: find Sean Meyer and stop him - by whatever means necessary.
