The Darkness Of Ragnarok: Shadows of Midgard

A terrible comet storm, Ragnarök, is being tracked by NASA and should pass the galaxy undisturbed. Nonetheless, in a cataclysmic turn of events foretold by Norse mythology, the storm forcefully hits our planet, re-ordering the cosmos as the sun is drawn out of orbit and leaving Earth in consumable darkness.
Unbeknownst to a team of scientists assembled by the US Government, they have a crucial role to play in the regeneration of light and the survival of their fellow species. The thirteenth crystal skull that combines the collective consciousness of the gods' worlds must be found, and as experts in their field, Deena and Dan must complete their mission.
In a race against time as darkness empowers the evil entities, faith and courage will be tested and mysterious ancestral forces challenge every conceivable grip on reality. Whether the scientists can restore light on Earth remains a colossal challenge, and whether they'll be any survivors left poses an even greater one.
