How much sacrifice should anyone have to give? Petal and Gabriel are forced to decide, as the mad, digital entity, Elliot Robertson, is determined to dominate the world. His influence, spread by an insurgent group, The Ronin, seeks to control and enslave the last of humanity. With time running out, Petal and Gabriel must travel to the far reaches of the abandoned lands in order to repair a server they believe will be the key to defeating Elliot and his ronin. All the while, Petal has a ticking time bomb inside her head: Gerry Cardle's uploaded consciousness. The code of which is mutating, but to what end? Together with their few allies, Petal and Gabriel must face either victory or total annihilation.

Rogue hackers Petal and Gabriel are low on food and water. Their reputation precedes them and they are no longer able to hustle the crime community for supplies. With survival becoming harder, they’re left with no other choice but to accept a risky job from a dangerous individual.

In a post-apocalyptic future, humanity survives within a single domed city ruled by a shadowy organisation known as The Family. Gerry Cardle reluctantly runs the Death Lottery. It's a job he despises, yet one which keeps his name off the list. Until one day, despite his agreement with The Family, his name is inexplicably drawn next.

Being human is no longer enough to save humanity. The fanatical Red Widows sweep destruction across the abandoned lands. Their aggression threatens to destroy the city Gerry had risked his life to save. Petal, the woman Gerry has come to love is dying. The despotic cabal, The Family, demand he brings her to them, but she's missing, running from the Widows, searching for the truth of her origins before it's too late. When their paths cross, Petal and Gerry will hold the fate of humankind in their hands—if they can survive the malevolent digital entity that stalks them from the shadows. Assembly Code is a post-apocalyptic, near-future thriller that will delight fans of The Matrix, Neuromancer, and Blade Runner.
