Harlan Coben never fails to keep you guessing and Shelter is another classic example, although perhaps more targeted at a younger audience than his other novels. I have only seen six episodes so far but have found it very entertaining, and as usual haven't got a clue how it will turn out in the end. If you don't like Harlan Cobens style of writing (like all authors he has his own definitive style) then give it a miss, but if you do enjoy his plot style you are in for a treat.
