When Zen – one of the most advanced cyborgs in the world – catches a hacker inside her own company, the last thing she expects to find is her replacement. Adam is another full-body cyborg, the cutting edge of cyberisation – but he isn't an Eidolon, and he's following orders no-one else can hear.

Soon, Adam is in charge of a mysterious new unit, Carmine district is for sale to the highest bidder, and QuanCorp is spearheading a new technology that sounds suspiciously like mind control. Zen must unravel the conspiracy that ties it all together, and risks destroying the newfound autonomy of the Eidolons.

And this time, to eliminate the threat, she's going right to the top.
