When college student Emery Driscoll is blackmailed into being a courier for a clandestine organization, she's cut off from the neural implant community which binds the domed city of New Worth together. Her new employers exploit her rare condition which allows her to carry encoded data in her blood, and train her to transport secrets throughout the troubled city. New Worth is on the brink of Emergence-freedom from the dome-but not everyone wants to leave. Then a data drop goes bad, and Emery is caught between factions: those who want her blood, and those who just want her dead.
