Humanity will face a new Ice Age in the second half of the 21st century. But the rapid cooling and the advance of glaciers are not the only calamity. Much more terrifying is the gradual fading of the human mind.
Humanity has split into three large groups: cognitively impaired dubecephals, aggressive adaptants who have successfully adjusted to the new realities, and normal people. And then, in Moscow—snowed in up to the third floor—war begins. “Normals” try to survive and win. But what is permissible and what is not in this struggle? Can we treat adaptants as people? And if we cannot—if in the fight against them everything is allowed—will we still remain human ourselves?
