When a late night altercation on a Belfast mountaintop leads to murder, all the evidence points just one way. Boston. Faced with the news that the victim was likely Terror, Mark Shaw must grapple with events in his recent past that are a mystery even to him, in order to uncover the truth.
As the discovery of other bodies places the identity of the first victim in doubt, what begins as a holiday for Shaw and his family soon becomes a nightmare as events on either side of the Atlantic conspire to threaten their future and tear the very fabric of Farset Investigations apart.
With a team broken by their own actions and divided by those of others, they are far from prepared for what lies ahead, but face it they must. A sinister act of revenge from cult leader, The Prophet brings with it child abduction and tragedy, whilst new murders bearing links to Terror and his followers bring with them a shocking realisation with global ramifications.
In this, the chilling conclusion to the Terror trilogy, Mark Shaw must first heal his broken team before leading them through the most dangerous fight of their lives. A fight that will bring them directly back into the evil world of Terror and onto an inevitable collision course with cult religious group, The Enlightenment.
The question, will they be victorious and if so, at what cost?
