A huge part of this story plays out in the Middle East, full of private contractors and fixers. I was pretty impressed by how well this world was portrayed, obviously well-researched.
Fox is as ever one of the best female thriller protagonists as she is a very tough woman, yes maybe a female Reacher of sorts, though more human. She's not a quirky, witty kind of investigator nor is she a man with boobs. Although for me this one strayed a bit too much from the kind of hardboiled crime fiction into thriller territory for my tastes it does contain some great action scenes and good characters.
