It really does exist - It’s a super volcano simmering just beneath the surface of Yellowstone National Park - It has erupted in the past, and will erupt again - Scientists believe that when it erupts again it will destroy 20 percent of the United States - You do NOT want to be in that 20 percent Tony and Hannah are just a couple of high school kids who happen across a woman who will change their lives forever. She’s a carnival fortune teller who warns them of a great calamity soon to befall the United States of America. The old woman tells them it will be up to them to tell the world of the impending danger. And to save the lives of millions. It would be easy to dismiss her warnings as fantasy, except for the fact that she vanishes before their very eyes. And so begins a long journey for Tony and Hannah. A journey which involves a great mystery, intrigue and danger. Not to mention threats by a government which should be trying to help them, but instead is trying desperately to keep its secrets hidden.
