FIRST, Patrick receives DVDs in the post. They show invasive footage of him and his wife washing, dressing, going to work – all taken by cameras hidden in his house.

Soon they find themselves questioning everything and everyone as their lives unravel. Someone is out to get them.

And then the emails start arriving: Tell no one, go alone. Do what we say. OR SHE DIES.

Patrick’s life is turned upside-down. Suddenly, this is a matter of life and death. He must follow the instructions to survive.

The story, with more twists, turns and gasp-out-loud moments than you could ever imagine, will have you whipping through the pages.

I simply could not put it down.
