Home World: Undying Mercenaries, Book 6 (Unabridged‪)‬

The Galactics arrived with their Battle Fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined a vast empire that spanned the Milky Way.

When the Earth is invaded by a rival empire, James McGill's legion must defend the Home World. The top brass has complex plans, but none of that matters much to McGill, who chooses his own unique path. Traveling to star systems no human has ever visited, he searches for a technological edge to beat the enemy before it's too late. Along the way he unleashes new terrors, triggering the biggest battles in human history.

Home World is the sixth book of the Undying Mercenaries Series, a novel of military science fiction by best-selling author B. V. Larson.
