21 Days Until the Apocalypse, or The Time of Broken Clocks

A St. Petersburg engineer, Vladimir Gromov, discovers that scientists' calculations contain a fatal error. An asteroid threat from the distant future crashes into the present. In 21 days, he must confront government indifference, societal panic, and his own fears. This is a story of the end of the world seen through the lens of one family, where time becomes the most precious and merciless enemy.
When the world collapses, the choice becomes unbearably simple: flee or stay? Save humanity or protect your loved ones? Together with his wife Catherine, children Kira and Miron, astrophysicist friend Oleg, and godfather Bratislav, Vladimir embarks on a desperate journey to an underground shelter that will eventually become their city—"Gaea."
But the apocalypse is not the end. Years later, the characters encounter a new mystery: a mysterious blue capsule from the sky brings not only a threat but also a chance to heal the dying planet. Under an Alien Sky, they must reconsider the boundaries between human and incomprehensible, between science and faith, between fear and trust.
Three intertwined stories about one family, separated by time but united by an unbreakable will to survive.
