A Huli is an ancient Chinese werewolf, two thousand years old. She doesn't just tell the story of her life in Moscow among tailless monkeys, but also writes a Holy Book: 'It is believed that it will reveal the main secret of werewolves. Every werewolf who reads it will be able to understand this secret five times over.' A Huli is a master of illusion, but one day she encounters someone who is beyond her hypnosis: a werewolf with an FSB ID.
