When a brutal attack leaves a priest close to death and screaming of dark prophecies, Professor Alex Harker once again finds himself pulled into the shadowy world of the Magi.
On dubious pretenses, Harker must join a desperate search for the missing child he has sworn to protect.
But as he edges closer to the truth, he realises the child's importance pales in significance to the cataclysmic events unfolding around him. When reality and prophecy start to merge, and nations begin to crumble, Harker knows the future of the planet is in his hands.
Its salvation lies in the discovery of one thing: The 4th Secret.
A heart-stopping rollercoaster that won't let go, R.D. Shah's brilliant thriller is perfect for fans of Dan Brown, Scott Mariani and Chris Kuzneski.
