The weight of the water was equivalent to the volume generated by the Mississippi River times 22. It challenged an already fragile seismic system consisting of hundreds of active faults.

In the not too distant past, along the Mississippi River, North America tried to tear itself in half. It failed. It won’t the second time. The New Madrid fault zone, six times larger than the San Andreas in California, has generated a series of massive earthquakes thrusting the Atwood and Chandler families in a fight to survive. Will they arrive for Christmas? Will they arrive at all? Their lives are about to change forever. Prepare to be shaken.
