Hell World

Undying Mercenaries, Book 25

By: B.V. Larson

Narrated by: Mark Boyett

Four hundred degrees! Toxic atmosphere! Gravity beams that crush men in armor like beer cans! Welcome to Infernus.

Legion Varus assaults an alien stronghold that's too close to Mother Earth. The battle turns into a meat grinder that chews through soldiers faster than revival machines can spit them out again.

When enemy reinforcements approach the star system, the campaign becomes a race against time. Centurion James McGill must defeat the Demons and their minions before it's too late. He teams with old friends and old enemies. Robots, Blood Worlders, and Saurians join the fight in a grand battle on a deadly planet.

Then McGill meets the entity that is behind the invasion, changing everything…

Hell World is the latest action-packed entry in B.V. Larson's bestselling Undying Mercenaries series.

Love the series

I have listened to all of this series and absolutely love the books. If you enjoy military science fiction then you will love this series

love it!

thank you sir, may I have another? more of everything I love. surely one day I'll get sick of these characters but that day ain't today!

The saga continues

I hope the author has at least one more book for this series before running out of new world ideas…the narrator does a great job.

He gets punished by everyone

He gets punished by everyone when he saves Earth multiple times, he should be untouchable as a soldier leader!

book 25 keeps on giving

so I've listened to all 25 books so far.
sometimes I think in these long series some authors are mailing it in, but not so in this case. I was struck by the vivid imagery and the effort that it takes to create. keep up the great work.
maybe you can give ole McGill a promotion?
