A thirty-year stalemate between humanity and the Psion AIs is ending...

But the AIs have not been idle. Their agents are everywhere and the seeds of rebellion and dissent have taken root. Humanity’s home system is a powder keg, and when the match is lit, all of Sol will erupt.

Cara has been in prison for four years, her mind numbed by docility, unaware of what's been brewing. When a mysterious agent breaks her free, she finds herself caught up in a web of intrigue, double-dealing, and political machinations.

The Sykes family saved Sol from a human-AI war once before. Now it's up to Cara and her sister Lyssa to turn the tide, and keep the galaxy’s two dominant species from tearing one another apart.
