Baron Lucius Giovanni has done the impossible: not only has he held the alien Chxor at bay, he has taken the fight to them and liberated human worlds. Yet humanity's implacable foe has drawn a line in the sand. They will hold Nova Roma at all costs... or see it a scorched ruin. Lucius must aid Nova Roma's Emperor and liberate his homeworld, but along the way he must also deal with old and new adversaries and with a conspiracy that seeks to usurp control of his fleet. Conclusion of the The Lightbringer Trilogy.
