THE MOST INFAMOUS CRYPTID EVER TO CAPTURE THE IMAGINATION OF THE PLANET... A MAN PUTTING HIS LIFE AT RISK... When evolutionary biology professor Dr. Zack Hitchens loses his wife in a senseless accident, he decides to follow her dreams all the way to the roof of the world—the peak of Mount Everest. On the infernal mountain, Zack and his teammates battle sickness, whiteout conditions, avalanches, the oxygen-starved minds of other climbers - and something else. Something primitive and consumed with rage. Something seeking revenge... Something downright abominable.
