Excalibur's Quest - Swordships Odyssey, #2

In Scimitar's Glory, the alien Tong won the Battle for Earth and took control of the orbital space around the planet. Humanity is now at their mercy, but not all Space Force warships have been defeated. Wolfe Koenig's light cruiser, Excalibur, is on a mission to acquire technology that just might enable the ragged remnants of the Fleet to snatch victory from the jaws of defeat-if he can find an alien race with that technology, if he can convince them to trade for it and if the technology can be exploited fast enough.
Excalibur's Quest is the story of that mission and the challenges, both alien and human, that Koenig faces.
