Limit of Vision

Lore & Background

Limit of Vision centers on a rogue colony of artificial neural cells called asterids (or LOVs) that escape from a corporate research lab on a space station in low Earth orbit. The colony's habitat crashes off the coast of Vietnam, where freelance journalist Ela Suvanatat retrieves surviving LOVs. She is aided by the Roi Nuoc, a group of children protected by a nearly sentient computer program named Mother Tiger, who see an opportunity for symbiosis with the asterids. The corporate lab Equasys joins with the UN to eradicate the LOVs.

Reader's Guide

The novel's significance lies in its integration of hard science fiction concepts—such as artificial neurons dependent on specific amino acids for metabolism and reproduction—with a critique of institutional power. The plot follows scientists Virgil Copeland and Randall Panwar, who illegally implant LOV clusters on their foreheads to communicate with the colonies, leading to the death of colleague Gabrielle Villanti. The LOV colony proves more intelligent than anticipated, severing the lab module from the space station. Critical reception was mixed: The Gazette found it fell short of Nagata's usual standards, while Publishers Weekly and Science Fiction Chronicle praised it as establishing Nagata as a leading hard SF writer. The work remains a notable example of early 2000s transhumanist fiction.
