Everything's going to plan - until someone steals his life...

With a lucrative job, great marriage and a beautiful house, Bill Moore is a man with a plan. It's all working out just fine, until the day he finds a card left on his desk, printed with just one word: MODIFIED.

From that moment, his life begins to change - at first barely noticeably, then in more and more disturbing ways. Bill soon finds out, in the most terrifying way, that he has become the subject of a dark and deadly game . . . and that he has no choice but to fight back.
