In 2090, climate change, war, and a virus called the Retrophage have ravaged humanity. Most children are stillbirthed, and those who manage to survive are born with a host of defects. Only Gen-perfects, children artificially engineered and grown in artificial wombs, are free from the devastating effects of the Retrophage. A technology exclusively controlled by Bioloxys.

When she learns of the possibility of a ring of implant harvesters, she heads into the lower city with Geraldo, a street-smart officer. Together they uncover an insidious plot that stretches into the highest levels of government, and all clues lead to Bioloxys.
