Rogue Guns: A Military Sci-Fi Adventure

Rate this book
Cut off from home. Hunted by an empire that wants them dead.

When the Ghost Protocol sealed the Gauntlet, it trapped Frank Cage and Martin Kelvin on the wrong side with nine Marines, a handful of Halcerite defectors, and no way back. Now, Black Horn kill squads have their scent, tracking their defector allies over a blood debt older than human civilization.

For Martin, the war is the least of it. The Hollow infection is eating him alive, rewiring his brain and body. Not quite human anymore, but maybe their one shot at raising an army of the enslaved. The plan they concoct is a desperate hit the empire where it bleeds, fight a guerrilla war they can't win head-on, and free the Hollow before the empire raises a monster far worse.

On the colony side, Thomas Kelvin is trying to keep his family alive while Eden burns under Halcerite warships. The planet is already lost. All he can do now is run, but escape won't be easy when it's not just the aliens who want them dead.

To survive, the men of Old Guns and Young Guns will have to become more than Marines.

They'll have to become Rogue Guns.

Frank Cage and Martin Kelvin are Old Guns

Restored to combat ready, the two Master Guns bring their trained New Guns and the Halcerite rebels, now Rogue Guns, in the fight of their lives. They carry the fate of the galaxy with them. Just the two Master Guns and their dogs with the best fighting force they could assemble against the World Eater. The end draws nigh!
Great characters raised against an awesome storyline, with amazing action! Blood, guts, sacrifice and glory await. This is a great read!
