Zach Reeves, a self-taught 20-year-old living in a Croydon council flat with his night-shift nurse mother, finds a classified document on a government server. It reveals Project Meridian, a secret programme to monitor and control every financial transaction in Britain.

He teams up with Lily, a data science student; Jane, a care leaver from Manchester; and Steve, the son of a Hungarian intelligence officer. Hacked, hunted and betrayed, they fight an enemy with no public name or face. One of them is taken, and the others must decide how far they will go to get her back.

The conspiracy may be bigger than they realised, and the exposure they fought for may have been part of the plan.
