"Six days ago, Joe Lynch was a happily married man, a devoted father, and a respected teacher living in a well-to-do London suburb. But that was before he spotted his wife's car entering a hotel parking garage. Before he saw her in a heated argument with her best friend's husband. Before Joe confronted the other man in an altercation where he left him for dead, bleeding and unconscious. Now, Joe's life is unraveling. His wife has lied to him. Her deception has put their entire family in jeopardy. The man she met at the hotel has vanished. And as the police investigate his disappearance, suspicion falls on Joe"--

It's the evening drive home from work on a route Joe Lynch has taken a hundred times with his young son. But today, Joe sees his wife meet another man, an encounter that will rip two families apart. Joe will do whatever it takes to protect his family, but as the deception unravels, so does his life. A life played out without any rules. And a cunning opponent who's always one step ahead.
