Monstrosity. Panktown

Welcome to the city of Paxton on the planet Oasis in the distant future. This is a huge megacity that locals have long referred to as Panktown. Here, people live side by side with various alien races: plague with huge... mouths, strange tikikhotto with tentacles instead of eyes, l'leveds whose bodies resemble melted wax, and many, many others. Life in this city is hard, but dying is easy. Here you can turn your clones into works of art, some districts are gripped by a strange viral cancer, you can erase memories, and alien rituals are astonishing in their monstrosity, but somehow you have to coexist with them. Everything can happen here: both beautiful and terrible. For example, the story of an ordinary clerk named Christopher, whose girlfriend jokingly decides to perform a ritual to summon a dark entity.
At first, everything goes without any consequences, but then his beloved begins to change. 
Soon, an ordinary person will learn that many alien races of Panktown are aware of the cult of horrifying creatures from other realms and dimensions, the cult of the Ancient Gods. And Christopher will have to learn the name of the book that his girlfriend used to conduct the ritual well. 
For even in a world of high technology, corporate warfare, aliens, and spaceships, the "Necronomicon", although long forgotten by humans, has not lost its power.
