Welcome back to the City of Dragons! Can you hear the icy wind howling? Do you sense danger in the air? How will you feel when you receive a letter from a mysterious stranger, in which she promises to drown the entire city in blood? A lively mind, a willingness to act and a desire to get to the bottom of the truth force the former student of Professor Stanton and her faithful household members to begin confronting the insidious plan of cold-blooded attackers. What is the reason for the death of the nun? What did the city's founding fathers warn their descendants about? Why did breaking these covenants have such dire consequences? Why did the Rusty Dragons once give their daughters to werewolves? There are more and more questions, and strange and frightening events are growing like a snowball. Miss Anabelle Vaerty continues her own investigation.
