Michal Aivaz is a modern Czech prose writer, poet, philosopher, and specialist in the works of Borges. He is called the heir to the traditions of Borges, Lovecraft, Kafka and Meyrink. Aivaz’s modern world is unreliable and unstable; through the thin veil of the visible, at every step something else appears - beautiful or terrible, but invariably strange. An antique book with mysterious writings that falls into the hands of the hero haunts him... And then one day a random librarian reveals its secret. The book with these texts belongs to an alien world, which is located next to ours, but getting into it is not only difficult, but also dangerous...
