Couriers transport data and on occasion small objects for anyone willing to pay the price. Secured delivery is guaranteed and no questions are asked. Like having a human servant in this corporate owned world, using couriers is seen as a status symbol for the wealthy and corporate elite. Gangs also use couriers for the same reasons. This gives the hundreds of couriers in NYC steady work.
Zoe Blanco moved to New York after fleeing the small town she grew up in and the Purity Church that runs it. The Church believes in keeping humanity pure. This means none of the nanoPCs known as Frames or any other cybernetics that most of the rest of the world uses everyday.
After weeks of not finding a job while living with her aunt and cousin, Zoe turns to the mob so she can get a loan to pay for the secure storage space a courier needs and a frame for herself. After making an illegal run or two, Zoe finds employment with a transport company and truly starts her life as a courier.
