Crux

Kade Lane's role in spreading Nexus, a drug that links human minds, has come back on him. The Post-Human Liberation Front has taken the technology and turned it into a way of making recruits into living weapons. Governments are being pushed toward chaos as a result.

Kade and Feng, a genetically enhanced soldier, are on the run from the CIA. Their aim is to stop a full-scale war between baseline humans and the posthumans that Nexus is creating, and they have to do it while being hunted.

A second storyline unfolds in Shanghai. Ling Shu, a posthuman child, tries to free her mother, Su-Yong Shu, whose mind has been uploaded and is held as a computer intelligence on a Chinese government server. That thread builds toward an act of digital hijacking.

This is the second book of the Nexus trilogy and follows the events of Nexus directly. It is a technothriller with the bioethical questions of the first book now at the centre of a larger conflict, and it moves between two lines of action rather than following one hero.
