About the book: 2019 / Austria, 1461. Cities along the Danube are spontaneously seized by the dance plague. What is this - illness, insanity or obsession? Gregory's heroes - member of the secret Order of Darkness Luca Vero, servant Freise, priest Pietro, noble lady Isolde Lucretili and her companion Ishrak - do not know the answer. But we are ready to take risks and spin in a whirlwind of a crazy dance, continuing to explore the heresies of the world and the signs of its inevitable end.
