A talented musician, composer, director of a boys' choir, and he is also a maniac killer... It is unknown how many children's souls he would have ruined in his life if one day the main character of the novel, a scientist, a specialist in interdimensional vacuum, had returned from a long business trip , by chance I didn’t get to a boys’ choir concert and didn’t recognize my twelve-year-old self in the soloist. For middle and high school age.
