Revolution Radio

After a global revolution, the world is left in disarray. A new world order has begun, to pick up the pieces and to make sure that the ways of the old world remain forgotten. Comm Techs ("commies" for short) maintain all the communication channels via a complex inter-network of radio towers. They speak in code that no one else can understand, and they obsess over the "Godstream" - mysterious signals from the atmosphere that no one can quite explain. And then one morning, the daily broadcast doesn't arrive. And it's up to one reclusive comm tech to find out why.
