In his domain, wealth and beauty take all; frivolity begets cruelty; science and alchemy collide. From the Hall of Mirrors to the vermin-infested attics of the Chateau at Versailles, courtiers compete to please the king, sacrificing fortune, principles, and even the sacred bond between brother and sister.

    His only companions are the disembodied voice of Miranda Taligent, the only woman he has ever loved, and the cryogenically frozen body of her father Prospero, the genius and industrial magnate who drove her insane.The tale of Harold’s life is also one of an alternate reality, a lucid waking dream in which the well-heeled have mechanical men for servants, where the realms of fairy tales can be built from scratch, where replicas of deserted islands exist within skyscrapers.. As Harold’s childhood infatuation with Miranda changes over twenty years to love and then to obsession, the visionary inventions of her father also change Harold’s entire world, transforming it from a place of music and miracles to one of machines and noise.
