With the world balanced after the tragedies of the year before, two tribes attempt to come together and form a whole. But as an ancient foe from the past reappears and a new threat from the south snakes its way to them, the Stick People and the Cliff People must do more than put their differences aside. they must come together to survive. As fantastic as it is violent, The Cult of the Skull picks up right where The Enemies of Our Ancestors left off.
