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 huge computer game! This post-apocalyptic story 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! Deserted strongholds can wait a long time - as long as necessary. And their time has come. Twenty years after the Holocaust, the ancient Vyborg Castle again serves as a shelter for people. After sunset, something terrible happens behind its walls, and what is happening inside is not much inferior to the horrors of the night. But those who no longer have room in the St. Petersburg metro tunnels no longer have a choice. To continue their journey to the north, they will have to engage in battle with predators, and the most dangerous of these predators walk on two legs. Is it possible to remain human where there are wolf morals? Only those who answer this question correctly will be able to master a weapon that cannot be matched by sharp teeth or deadly steel.
