A mysterious message beckons Jack to a clandestine 'meet', but something is off. The code is identical to one his team used back in his Union days. When no one shows, he and Sara find themselves drawn into an investigation to uncover who sent the message... and why. It isn't long before they find a trafficking ring that snatches women from shelters and wipes their memories, all with the hope of selling them to the rich and powerful as 'wives'. But this is bigger than just a gang of criminals. There's an organization that stretches across both sides of the law with connections to elected officials at the very top.

The battle for the galaxy approaches. Under the guidance of the mythological gods, Jace must travel to Sarkonian territory in search of a woman he has never met. She holds the key to unlocking the Gate of Eternity, and with it, a weapon that may end the Celestials war against humanity. But nothing comes easy in a galaxy under siege. Even with the Alliance behind him, Jace and the crew have their work cut out for them. There are secrets still left to uncover, and the next battle could change everything.
