Comet Dust

Astonishing prophecies of the saints about The Warning, Three Days of Darkness, and more come to life in a supernatural thriller.
Eighteen months ago, the Earth survived a comet strike. Famine, economic depression, and soaring crime rates rode in on its tail. While the government scrambles for solutions, Gina Applegate vlogs about college life and current events. God doesn't figure large in her life. Nonetheless, Gina thinks she's a pretty good person until a mystical event called The Warning gives her a glimpse of hell, shaking her fragile faith. As the world slips deeper into darkness, the gulf between the godly and the godless widens, leaving no middle ground. Everyone must choose a side.
Before the comet comes, many nations, the good excepted, will be scourged by want and famine. The great nation in the ocean that is inhabited by people of different tribes and descent will be devastated by earthquake, storm, and tidal wave. It will be divided and, in great part, submerged . . . For in none of those cities does a person live according to the Laws of God. A powerful wind will rise in the North, carrying heavy fog and the densest dust, and it will fill their throats and eyes so that they will cease their butchery and be stricken with a great fear. ~Saint Hildegard (12th Century)
The actual prophecies upon which this novel is based are included at the end.
