Void Siege. Let the Galaxy Bleed, #2

First rule of guerilla war: never come out and fight in the open - but the Warp Wraith makes his own rules. More than half the planet of Circe is free, thanks to a rebellion backed by the Wraith's underground organization, the Revenants. Humans long-victimized by the tyranny of vampire overlords rally alongside off-worlders and lycanthropes pledged to the Wraith's cause of freedom for the galaxy. And otherworldly powers stir alongside war machines.
The Immortals of the Theocracy have no intent of giving up even one drop of blood, let alone a whole world. Already they gather fresh forces, both on Circe and beyond it in the icy expanses of space. Armored legions, space fleets, and horrors beyond mortal ken muster to crush the uprising. But the greatest threat to the Wraith's success may come from his own side; for vampires are not the only ones with a galactic agenda.
