Demon World

Undying Mercenaries, Book 24

By: B.V. Larson

Narrated by: Mark Boyett

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.

Another cliffhanger

You know what to expect if you’re a fan. If a a fun series that moves along nicely. I just hate waiting for the next installment. I suppose I’d call it binge worthy.

Fresh!

Fresh storyline. Harkens back to earlier books in the series. Original and entertaining. Suspenseful a bit scary even. Great fun

A new major Story arc!

For everyone else hooked on the series, this is a nice turn toward a new major story arc. The plot feels familiar but sets up a bigger story arc to replace the Clavers being out of the series.

best in series, can't wait for the next few books!!!

this one he adds a bit more to it and I think he is wrapping the series up maybe 2 or 3 books away but it's getting interesting!

very entertaining

As always very fun, can't get enough of this series, you always get a good story and the narration brings the book to life for me, I wouldn't listen to it otherwise.
