Sci-fi, aliens, corruption, crime, detective work, European feel, great mix of things. Great characters, surprises, keeps you wondering exactly who or what is behind it all and what their motives are. Really like the two main characters that are the detectives, really work well together ("usual" mix of quite different people). The aliens are something different keeping sort of in the background and you do winder who is who and what's going to happen. Love the German setting, makes it better than if set in the good old USA that you might expect of such a thing. All in all a great take on aliens taking over people (or are they?). So pleased I came across this.
