"Bulbona" is a multi-layered novel that combines modernity, the 40s and 80s of the twentieth century and the timeless. In the center of the plot is the investigation of Bogdan Vovka, who is trying to find out the nature of a strange vision of the underwater world, which opens up dramatic pages of the past for him. The main conflict unfolds around flooded villages that went under water when they were building reservoirs for hydroelectric power plants. Despite the fact that most of the geographical names in the novel are metaphorical, it is based on folklore, memories and experience of residents of specific villages of Chernivtsi, Khmelnitsky and Kiev regions. In the image of the metaphorical Rybar River, residents of different regions of Ukraine will be able to see "their" river and their reservoir, and then their flooded villages. And everyone will have a different version — What kind of river it is and what kind of villages it is. But everyone has a common "experience of Atlantis", which once went under water with its beliefs, legends and passions — with everything.
