Following God Star, this is the second volume of Cardona's projected 6-book work on the theory that Earth was once a companion of a brown dwarf star, the remant of which we see today as the planet Saturn.

One of the big mysteries concerning Earth's recent history has been the cause of ice ages and what brought them to an abrupt end. Many theories have been advanced in the course of the last hundred years, but none has gained universal acceptance or proved entirely satisfactory. Following on from the hypothesis developed in God Star, Part Two presents the case that Earth’s last Ice Age and the planet-wide devastation and rapid mass extinctions that occurred around that time were results of the cosmic catastrophe following the entry of the proto-Saturnian system into the present Sun’s domain of influence.

As in God Star, support for these conclusions derives from the message left by the survivors in mankind’s mytho-historical record, and from scientific evidence written into Earth's geology of massive tectonic upheavals, geomagnetic field excursions, global vulcanism, and the incursions of oceans over continental land masses.

The roots of religious belief identified previously are explored further to show that recognition of the Saturn entity--originally accredited with the powers of a deity--as the agent of the world's devastation established the belief in humanity's subjection to a wrathful, vengeful god that has directed the course of so much of history's darker episodes since.
