Three qverse security experts--hackers, if you're being vulgar--have been hired to prove that you can't murder someone with the internet. Of course you can't, that would be nonsense, but one of the companies in charge of the billion dollar system needs investors and the public to be reassured. This is how Regina Carter, Felix McGuiggan and Lloyd Hong meet, but not for the first time. As clues pile up and mysteries twist and tighten around one another, the hacks find themselves in the middle of something much bigger. With reality blurring and sinister forces guiding their digital hands, the qverse itself could be at stake. Or it could be the problem.
