This work, the smallest in format, is the fourth in a series consisting of five separate and independent science fiction novels, interconnected only by a single idea and collected into one whole under the general title “Quintet. Worlds." This book is not so fantastic as mystical in nature. The author tries to reflect in it the complex theme of creativity, spiritual experiences against the backdrop of mundane and cruel realities. It seems that this novel is completely different from the previous ones, but it is related to them in spirit and meaning. The worlds do not necessarily have to be different from each other due to the discrepancy between time and space. Everything is one in the Universe, everything is interconnected, and as the author has previously repeatedly stated, the worlds are inside us, and not outside. But the most important thing is different. Who knows whether an angel or a demon will overcome a person? Yes, and most importantly! This novel, as always, is primarily about love.
