Snowman

Among the most significant events of the 20th century, three stand out: man visited space; man visited the moon; man realized that he is not the only possessor of intelligence on Earth.
Years have passed. It is the middle of the 21st century on the planet. Humanity is on the brink of extinction. Nuclear winter rages. Officially, hominology is classified as a pseudoscience, but in reality, it is an essential scientific discipline, as its object of study is real.
This story is about a real snowman. About a creature that has learned to hide, survive, and travel through other dimensions.
