Russia, 1926. The Red Terror has reigned for years with secret police, forced labor camps, and executions now a part of everyday life. Stalin's desire for inhuman super soldiers fuels Dr. Ilya Ivanovich Ivanov's obsession with creating a human-ape hybrid—but to horrific ends. When Yuri Grechiko, a member of the state secret police, falls in love with a human experiment from a labor camp, he risks it all by fleeing with her to freedom on the Ural Mountains.
There, a boy and girl are born—neither human nor ape. An experiment Ivanov ever knew had succeeded. Vowing to keep it that way, Yuri hides the children from the mad scientist and raises them as his own.
But Yuri's past returns to haunt him. As Stalin's secret police climb the mountains, Yuri's world is shattered. From the horror of shocking experiments and devastating civil wars comes Micah, a gentle forest giant.
The mountains will tremble as he seeks his retribution.
