Scrivings have brought enormous progress and enormous wealth - but only to the four merchant Houses who control them. Everyone else is a servant or slave, or they eke a precarious living in the hellhole called the Commons. There's not much in the way of work for an escaped slave like Sancia Grado, but she has an unnatural talent that makes her one of the best thieves in the city.
