About the book: 2024 / Post-apocalyptic period on planet Earth. Mutants - people and animals who survived the biological “end of the world” - have adapted to new living conditions. But Martian colonists, whose ancestors fled from their agonizing home planet 150 years ago, decided to return to Earth. They face a difficult choice: to allow those who have earned this right to live in an unequal struggle with the agonizing planet, or to sacrifice their lives in the name of the purity of the human race? However, such a choice may be the least of their problems. The threat of invasion literally looms over the Earth. Creatures with highly developed, cold and insensitive intelligence have their own plans for the Earth and its inhabitants.
