Hellmarine 4: One Shall Crumble

Rate this book
The cycle was never meant to be broken... until now.

Deep in the shattered remnants of a dead moon, an ancient artifact pulses with Supernal Energy—power from before the Multiverse itself. The Hellmarine and his battle-scarred Stygians have stumbled onto a secret that Heaven would kill to possess and Hell would burn worlds to claim.

But in the space between spaces, where nightmares older than demons writhe in eternal hunger, the Archduke himself delivers a terrible Whoever slays the beast becomes the beast.

Now, with the Heavenly Host descending like vultures and reality itself bending under the weight of forbidden power, the Hellmarine must navigate a conspiracy that spans from the lowest pits of Hell to the highest thrones of Heaven. Alongside him stand those who refuse to let him a genius xenobiologist who anchors his humanity, a Ghost AI who defies her own limitations, an exiled angel questioning everything she once believed, and a squad of Marines too stubborn to die.

He is the Hellmarine, and he will not kneel to fate.

It is done

A great finale to an epic series. Taking on new foes and even greater threats than before, this is a fantastic bookend to one of the only series I have bought physically at the moment. Mysteries are solved and those working in the shadows are beaten into the light, with the baddest group of soldiers around. Great end for a great series.

An awesome series!!!

If this is the end I will truly miss this series! It really was an epic adventure with a great blend of fantasy and science fiction seamlessly blended together!!! My vote would be for more or at least keeping this world rolling!!!
