Lucas is a loner, but he's never alone.
From secret hiding places, he peers into the lives of others--watching them while they work, while they commute, while they sip their morning coffee. He is a master at remaining silent and unseen in his carefully constructed world as an invisible observer.
But when a chance encounter turns the tables, the watcher becomes the watched. Caught up in an escalating series of events he is powerless to stop, Lucas discovers an underground organization with a chilling mission.
Anyone can be watched. No one is safe. And the most terrifying secrets of all remain Unseen.
Until now.
