The Commonwealth has won a great victory, smashing Wolfbane's attempt to take Corinthian and driving Admiral Singh's forces back into enemy space.  Now, as the Wolves reel under the impact of their defeat - and powerful factions plot to take control of the government and military - Edward Stalker plans a final offensive to bring the Wolves to their knees.

But as mighty fleets clash in the inky darkness of space, infiltrators struggle to weaken a tottering edifice and both sides brace for the final confrontation, it all comes down to the last Terran Marines and a battle that will determine if the galaxy is to be united once again ...

... Or thrown headlong back into a new Dark Age.
