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 factions: Green - who are still trying to save the world; Blue - who try to profit while they can, and Black - who see no hope left.

When a group of extremist Green activists hire them for a series of jobs ranging from robbery to murder, Charlie - who struggles to feel anything except Black - wants to walk away. But Parker still believes they can make a difference, and urges her to accept.

As they enter an escalating biological arms race against faceless corporations, amoral biohackers, and criminal cyberpunks, Charlie will have to choose what she believes in. Is there still hope, and does she have a right to grab it?
