In the flourishing metropolis of Soot City (a fantastical version of 1920s Chicago), progressive ideals reign and the old ways of magic and liquid mana are forbidden. Daisy Dell is a Modern Girl – stylish, educated and independent – keen to establish herself in the city but reluctant to give up the taboo magic inherited from her grandmother. Her new job takes her to unexpected places, and she gets more attention than she had hoped for. When bounty hunters start combing the city for magicians, Daisy must decide whether to stay with her new employer – even if it means revealing the grim source of her dazzling powers.
