Charlie and Parker are punks by night, biohackers by day, living in the stuttering decay of near-future climate-collapse London. They pay for the beer they don't steal with money from their sketchy astronomy site Zodiac Code, while Charlie's bio-bespoke augments equip the criminals, punks, and eco-warriors of London. They have to deal with disgruntled clients, scene kids who don't dig their band, and a city that's run by corporates and criminals. Their world is split into three Green – who are still trying to save the world; Blue – who try to profit while they can, and Black – who see no hope left.
