Piter (Russian: Питер) is a novel that is part of the Universe of Metro 2033, a long-running series of short stories, novellas and novels written by different authors and set in the world of Metro. Piter, written by Russian author Shimun Vrochek, was originally published in February of 2010. Although there is currently no English version of the book, Piter has been translated into a number of other languages. The novel was translated into Polish by Paweł Podmiotko and published in Poland on the 9th of Novemeber, 2011. Joan Josep Mussarra Roca worked on the Spanish version.
The book itself is a bit different from Dmitry Glukhovsky's original works, giving the reader a look at what happened after the catastrophe in another part of Russia, whilst maintaining the original ideas and atmosphere behind Metro 2033. It's one of the longer novels in the Universe series.
Just like the people of Moscow, a fraction of St. Petersburg's citizens have fled to the underground tunnels of their hometown's metro. Piter (named after a Russian slang word for St. Petersburg) tells the story of Ivan Merkulov, a twenty-six year old fighter/stalker who experiences many trials and adventures as he travels through places both in the subway system of Saint Petersburg, as well as those above on the surface of post-apocalyptic Earth.
The novel begins with the young Ivan Merkulov about to get married. Unfortunately, his ceremony gets interrupted when the engine-generator that powers the necessities of life on Vasileostrovskaya (Ivan's home station) is stolen. Sozonov - friend and member of Merkulov's team of stalkers - believes that the residents of several nearby stations, who originate from Moscow, are responsible for the crime. Thus a war between those stations and an alliance that Vasileostrovskaya is part of begins.
As is revealed later on in the story, things are much more complex than Ivan could have ever foreseen. It turns out that he is dragged into something much bigger than the local conflict between the two factions, and the lines between friend or foe become very blurry as he continues his task. Merkulov's mission takes him to various locations, through numerous dangers and oddities, as he travels into the metro and beyond.
