Do we have a deal?CHAOS and RETREAT. A vastly superior alien race boils out of the galactic core. Cordez' research teams leap generations in months to find the technology they need, working out of the giant Prometheus base on one of the moons of Neptune.
But the people of Earth are forced back, until their planet is on fire from end to end, and they discover that their ideas about Humanity's origins are all wrong. MEDIEVAL PLANET. The Alliance is pushed back to a toehold on a few planets. Civil war rages across the medieval planet Hud, and Celia's research team closes in on war machines that might just put the Alliance back in the fight. ANTARES CRUCIBLE.
It has taken four years of research and invention to build the Alliance of Planets into a force to take on the rapacious Navscar cell from the core of the galaxy. But why were we transplanted to Earth millennia ago? What caused the Caerbrindii to split into three constantly warring races? And how can the Alliance destroy the alien city in the Antares sun?
