Humanity stands on the brink. Again. Surviving the Syndrome meant genetically modifying almost every person on the planet. But norms and gems are different. Gems may have the superpowers that once made them valuable commodities, but they also have more than their share of the damaged, the violent and the psychotic. After a century of servitude, freedom has come at last for the gems, and not everyone’s happy about it. The gemtechs want to turn them back into property. The godgangs want them dead. The norm majority is scared and suspicious, and doesn’t know what it wants. Eli Walker is the scientist charged with deciding whether gems are truly human, and as extremists on both sides raise the stakes, the conflict descends into violence. He’s running out of time, and with advanced prototypes on the loose, not everyone is who or what they seem. Torn between the intrigues of ruthless executive Zavcka Klist and brilliant, dysmorphic gem leader Aryel Morningstar, Eli finds himself searching for a truth that might stop a war.

When confiscated genestock is stolen out of secure government quarantine, DI Sharon Varsi finds herself on the biggest case of her career... chasing down a clever thief, a mysterious hacker, and the threat of new, black market gemtech. Zavcka Klist, ruthless industrial enforcer, has reinvented herself. Now the head of Bel'Natur, she wants gem celebrity Aryel Morningstar's blessing for the company's revival of infotech – the science that spawned the Syndrome, nearly destroyed mankind, and led to the creation of the gems. With illness in her own family that only a gemtech can cure, Aryel's in no position to refuse. As the infotech programme inches towards a breakthrough, Sharon’s investigations lead ever closer to the dark heart of Bel'Natur, the secrets of Aryel Morningstar's past... and what Zavcka Klist is really after.

The gillungs – genetically modified, waterbreathing humans – are thriving. They’ve pioneered new aquatic industries, and their high-efficiency quantum battery technology coupled to tidal turbines in the Thames estuary looks set to revolutionise the energy industry. But as demand grows, so does fear of what their newfound power might mean. Then a biohazard scare at Sinkat, their London headquarters, fuels the opposition and threatens to derail the gillungs’ progress. Was it an accident born of overconfidence, or was it sabotage? DS Sharon Varsi has her suspicions, and Gabriel sees parallels in the propaganda war he’s trying to manage: politicians and big business have stakes in this game too. And now there is a new threat: Zavcka Klist is out of prison. With powerful new followers and nothing to lose, she’s out to reclaim everything they took from her.
