About this listen

When Earth's colonies go silent, Legion Varus drops onto Kepler-62 expecting a routine investigation. Instead, they find something far worse than death.

The colonists aren't dead—they're changed. A new kind of enemy has arrived in Province 921, microscopic invaders that transform humans into perfectly coordinated killing machines. These "Demon" parasites don't just control minds; they improve them, creating an army that works with terrifying efficiency.

As cities fall and soldiers turn against their own, Centurion James McGill discovers he's mysteriously immune to infection. But immunity comes with a price. To save humanity from becoming pawns of a new Galactic species, McGill must navigate a web of seduction, betrayal, and impossible choices.

Some invasions come with warships. Others come with a whisper, a touch, and a promise of something better. The question is: what happens when the enemy might be right?

Demon World is an action-packed entry in B.V. Larson's bestselling Undying Mercenaries series.

Same formula. same script, but I still love it. Mark Boyett is James McGill. I dont think reading the book would be the same as listening to it. Mark really brings it to life. I would prefer more Galena Tourov she is one of my favourites and hope to hear more of her in the next book. If you are a James McGill fan im sure you will enjoy this book I did.

still love it.

liked the new direction but also disliked the continued distrust of McGill. after all the controversy the higher ups would be working with McGill now not constantly fighting him

continuing excellent content
