She deserts the League and heads incognito into the space of her former enemy, the Federation, in search of a new life.

The bad news is, it's the biggest pain in his ass, and she's stranded miles away.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

The alien race known as the Ancients vanished before Earth's last ice age - but not before building interconnected rings that form a highway system across the galaxy. Humanity has used these rings for years but has never figured out how to build its own, or even how to alter the connection pattern. Now, the Imperial starship Pandora is on a mission to discover and explore new interstellar connection points. While on Venus, an unexpected guest arrives - Marvin, a rogue robot who puts his strange mind to work on reconnecting the rings into a new pattern. Everything goes haywire.

Jack Four - one of 20 human clones - has been created to be sold. His purchasers are the alien prador, and they only want him for their experimentation program. But there is something different about Jack. No clone should possess the knowledge that’s been loaded into his mind. And no normal citizen of humanity’s Polity worlds would have this information. The prador’s king has been mutated by the Spatterjay virus into a creature even more monstrous than the prador themselves. 

The year is 2650. Seventy-five years ago, an alien fleet attacked Earth. Without warning. Without mercy. We were not prepared. Hundreds of millions perished. Dozens of cities burned. We nearly lost everything. Then the aliens abruptly left. We rebuilt. We armed ourselves. We swore: never again. But the aliens never came back. Until now. With overwhelming force the aliens have returned, striking deep into our territory, sending Earth into a panic.
