Lucifer's Children

In Aoyun's World the Technical War began in 1914 and ended in 1937. Science enhanced the weapons of war; and after the peace, after the plagues, the military AIs brought Humanity back from extinction into a peaceful and settled society ruled by clones of the old Imperials - Victoria, Cixi, Franz Josef, F D Roosevelt.

Shen Aoyun, an orphan bundled away into an Empire school in Shanghai, offered the opportunity to be introduced into Western Society on the Bund, takes her best friend with her to live with Lady Sophie and her diplomat husband Arisztid. But they are not what they seem, and Aoyun follows Jing into death, awakening as a Vampire. Blood and revenge fill her life until she meets Wilbur, a human who knows what she is - a victim, a casualty of the Technical War and its astonishing inventions.
Together they travel to London, trailing blood behind them, to meet the android who could help or destroy them, Professor Abraham Van Helsing. He changes Aoyun's life, giving her a mission to save the world from an alien who has acquired the power of the old war, to cleanse the Earth and bring his own people to enslave the survivors.

In the Carpathians, high above Sibiu, Castel Dracul hosts The Scholomance, a legendary college ruled by the Master. Eight monsters vie to win the right to ride the last dragon, and to usher in the end of the world. Aoyun's task, to find out what is really happening, is rapidly eclipsed by the brutality of the Master. Death stalks the Scholomance, blood soaks the dark streets of Sibiu. In the night her own dead mother arrives to shatter her sanity; and deep in the mind of a dying werewolf Aoyun's grandparents lie in pools of blood. Truth and lies, dreams and cold reality unravel beneath the radioactive remains of Bonn, where Aoyun's greatest challenge waits. Lucifer's Children have flown away, but their guardian has not.
