This most recent addition to the Atticus Kodiak series is (in my opinion) the best so far. The unusual premise for this main character — he’s a professional bodyguard — might have been short-lived, but Rucka comes up with a twist that turns everything on its ear and promises the next book will be something special. The ballet theme was maybe a little bit of a stretch, but that was the only slightly off point for me.
Of course, I know nothing about this kind of thing in real life. It may be badly flawed for all kinds of reasons, but in this case, for me personally, the story is what matters.
