“Metro 2033” by Dmitry Glukhovsky is a cult science fiction novel, the most discussed Russian book in recent years. Circulation - half a million, translations into dozens of languages, plus a grandiose computer game! This post-apocalyptic story has inspired a galaxy of modern writers, and now they are together creating the Metro Universe 2033, a series of books based on the famous novel. The heroes of these new stories will finally go beyond the Moscow metro. Their adventures on the surface of the Earth, almost destroyed by nuclear war, exceed all expectations. Now the struggle for the survival of humanity will be waged everywhere! What could be more important for the survivors of the nuclear madness that destroyed the world than a bunker? Shelter. House. Fortress. And what could be more important for a bunker than a door? Massive hermetic seal with a heavy “wheel”. He is the border between the safe “here” and the deadly “there”, the terminator between two worlds. But is the outside always an enemy, and is the inside always a friend? Who are you standing at the door?..
