What would you do if you discovered that the most catastrophic event in human history was less than a week away, and nothing could stop it? Something that would make all previous bloody battles, natural disasters, famines, and plagues seem trivial in comparison; something that hadn't shown its ugly face for at least 65 million years; something that mankind was not meant to survive. Fortunately, when adversity is at its peak, true heroes surface, and the greatness in men shines through the darkness to light the way for the rest of us...but, remember that evil can surface as well, so be careful whom you choose to follow. After Michael Hanson saves a young woman from a violent encounter with her abusive husband in a small Nevada town, they attempt to find refuge in another city. But, as they flee, the couple doesn't realize that they're about to be pulled into a life-threatening adventure in an event that will change the course of human history in less than a week. Michael, his two brothers, and a brilliant scientist piece the puzzle together and realize that the bizarre and frightening changes occurring at Yellowstone National Park are simply the tip of the iceberg, and that man is now facing something that is truly beyond comprehension-something millions of times more powerful than anything the Earth has seen in 65 million years when the dinosaurs faced extinction. The three brothers and their families are caught in a desperate struggle to survive amidst a political cover-up and the panic that ensues when the details of the event are revealed to the world. The group must somehow summon the courage and intelligence to beat the ticking time bomb that will soon convert the United States into a wasteland and claim over a billion human lives worldwide.
