Magic is illegal in the city of New Victoria. That means that Supernaturals - werewolves, djinn, fairies, and more - have started an underground trade in potions and spells. As an impoverished fairy, you've joined that trade in hopes of earning a better life for yourself and your family: you've become a changeling, transforming yourself to resemble the human noblewoman Lady Constance Weatherby.
But there is more to New Victoria's high society than meets the eye, and you are not the only one hiding a magical secret. Which noble house conceals a werewolf? Which one has suspicious ties to the shady Potion Market? Not only that, but there are fairy revolutionaries fighting to reverse the laws that forbid magic, and spies among the nobility working for the same cause.
Will you join them? Or will you stay in the comfortable human life that you have made for yourself?
