Ario is a Cheat: somebody who designs and sells Cheat Codes to Gamerunners.
Rick is – or was – a gamerunner: someone who tests there are no glitches or bugs in the Maze, the computer game that is so much more than a computer game.
Then Rick’s father falls out of favour and Rick is forced – jettisoned – out of the safety of his home on to the dangerous streets of Undone and the outside world – a world of flesh-dissolving acid rain and ferocious, feral, roving gangs.
There Rick meets Ario and together they find a joint cause that will lead them into a terrifying and dangerous battle with Crater Inc., the shadowy, sinister and all-powerful company that created the Maze . . .
