On a warm Fourth of July in the quiet town of Byram Hills, Nick Quinn watches as his wife and daughter die in an unprecedented terrorist attack. Amid the disaster, Nick is approached by a dying friend who hands Nick an antique pocket watch.
Emotionally shattered and desperate, Nick takes the watch and is shocked to find himself propelled back in time to where he was an hour ago, before the attack on his town. Quickly stopping the course of events, his relief is shattered as life spirals in an even more tragic direction.
At the top of each hour, the watch sends Nick back two hours to live one hour again, a backwards march to relive each hour of his day. A twelve-hour journey providing precious but limited time to protect Julia and Katy and uncover the source of the ever growing threat.
But each time Nick thinks he’s solved the crime and secured the future, he uncovers new levels of deception, agony, and betrayal, ultimately revealing a far more sinister plot with unexpected players and grim, global consequences.
If Nick hasn’t set things right by the 13th hour, not only will his wife and daughter be lost forever to the chaos, but an even greater catastrophe will be unleashed upon the world.
