Picture a future where Earth, forced into a cosmic empire, trades its only asset—elite soldiers—to alien bidders. That’s the hook that makes this series a standout, pulling readers into a world where loyalty, survival, and a touch of mischief collide.
How Undying Mercenaries Began
B.V. Larson, a USA Today bestselling author with a knack for military sci-fi, launched Undying Mercenaries in 2013 with Steel World. Inspired by classic space operas and his love for pulpy, action-packed tales, Larson envisioned a universe where humans are both underdogs and indispensable warriors. His goal? To craft a series that entertains with relentless action while exploring what it means to be human in a galaxy that doesn’t care. Over a decade, Larson’s vivid imagination has fueled a sprawling saga that’s become a fan favorite.
The Heart of Undying Mercenaries
The series kicks off with Steel World, where James McGill, a college dropout turned mercenary, joins Legion Varus to fight on Cancri-9, a mineral-rich planet. Outmatched and undertrained, McGill faces lizard-like foes and learns about revival machines that resurrect soldiers, making them nearly immortal. In Dust World, McGill, now a Specialist, tackles a lost colony defying Galactic Law, unraveling secrets that test his loyalty. Tech World shifts gears to Tau Ceti, a bustling trade hub where McGill uncovers an invasion threatening the crumbling Empire. Later, Home World sees him defending Earth itself, choosing his own path against complex military plans.
Undying Mercenaries thrives on themes of resilience, survival, and the cost of immortality. Larson’s world-building paints a galaxy where Earth is a minor player, forced to serve alien masters. The revival tech adds a unique twist, raising questions about the value of life when death is temporary. McGill’s roguish charm and moral compass inject humor and heart, balancing gritty battles with lighthearted banter. Each book introduces new worlds and aliens, keeping the series fresh while advancing an overarching plot about galactic power struggles.
