I have to say, I really enjoy this series. The books may be short, but they are straight to the point. And no recap of the previous books, which is great if you are reading them out of order based on which one you find in your local library. Currently on a third one and enjoying it.
This one, I really liked. It was rather interesting to see who the intended victim was and why someone was so much after him. And I really enjoyed the few twists and turns, which the author managed to put into such a short book.
I also liked Sarah and Jack as characters, although they can be bit nosy. But how else can you get the truth, if you do not ask the questions? It is not like they could get the official police investigations, although in this case, there wasn't really any. Since it started with the accidents. Or were those accidents?
Personally, I can recommend this book.
