Marines: Crimson Worlds 1

4.0 Stars (474 Reviews)
Genre: Science Fiction & Fantasy | Science Fiction

Erik Cain joined the Marines to get off death row. The deal was simple; enlist to fight in space and he would be pardoned for all his crimes.

In the 23rd Century, assault troops go to war wearing AI-assisted, nuclear-powered armor, but it is still warriors and blood that win battles. From one brutal campaign to the next, Erik and his comrades fight an increasingly desperate war over the resource rich colony worlds that have become vital to the economies of Earth’s exhausted and despotic Superpowers.

As Erik rises through the ranks he becomes a deadly warrior, and he finally finds a home, first with the Marines who fight at his side and later among the colonists – men and women who have dared to leave everything behind to build a new society on the frontier, one where the freedoms and rights lost long ago on Earth are preserved.

But causes can be fleeting, imperfect things. Amidst the blood and death and sacrifice, Erik begins to wonder. Is he fighting the right war? And who is the real enemy?

The Cost of Victory: Crimson Worlds 2
by Jay Allan
4.4 Stars (226 Reviews)
Genre: Science Fiction & Fantasy | Science Fiction

The Third Frontier War is raging, and all across human-occupied space worlds are burning. Massive fleets struggle for dominance and kilometer-long war ships exchange thermonuclear barrages.

Battered in the early years of the war, the Western Alliance is resurgent. The brilliant Admiral Augustus Garret leads the Alliance fleet from victory to victory, taking the war to the very heart of the enemy empires. And on the ground, Colonel Erik Cain, hero of the Marine Corps, leads his crack troops again into combat, seeking the final battle.

But war is the province of more than soldiers in the line, and in the background, the secretive intelligence agencies of the despotic Superpowers plot and scheme, using their own soldiers as pawns in the great game for control of space.

The final battle will be fought in the reddish sands of a backwater world, where the rivalries of the Superpowers are about to become irrelevant, overshadowed by a staggering secret that has lain hidden in a remote cave for untold centuries.

All the Powers struggle for the ultimate victory, but at what cost?

A Little Rebellion (Crimson Worlds Book 3)
by Jay Allan
4.4 Stars (191 Reviews)
Genre: Science Fiction & Fantasy | Science Fiction

The Third Frontier War is over, and the Western Alliance is triumphant. All across human-occupied space, colony worlds celebrate the coming of peace. But peace is an elusive dream, and more trouble is brewing. The war was expensive, and the economies of the Superpowers, always fragile, are on the verge of total collapse.

The Directorate, the shadowy intelligence organization that has become the true power behind the Alliance government, plans to strip the colonies bare to pay the costs of war. Already, they are tightening their control over the freewheeling colonial governments. And the Marine Corps faces total destruction at the hands of the worst traitor in its history.

But the colonists are a different breed than the passive mob on Earth, and they have no intention of meekly surrendering their hard-won freedoms. On worlds all across the frontier, plans are hatched and weapons hoarded. And in taverns and meeting halls the words of an ancient text are uttered in hushed tones. A little rebellion, now and then, is a good thing.

A Little Rebellion is book three of Jay Allan’s bestselling Crimson Worlds series (over 800,000 sold).

The First Imperium (Crimson Worlds Book 4)
by Jay Allan
4.4 Stars (180 Reviews)
Genre: Science Fiction & Fantasy | Science Fiction

From the depths of space, a nightmare is coming.

The Alliance and its colonies have reached an uneasy peace, ending the destructive rebellion that had raged on a dozen worlds. No one expects the deal to last, and both sides are preparing for the next showdown.

But from another challenge is coming, a horror almost unimaginable, one that will endanger the very survival of mankind and force not just the Alliance and its colonies, but all of the Superpowers, to join forces or face annihilation.

The Alliance discovered dusty ruins on Epsilon Eridani IV, built by an ancient race, eons dead. But their guardians remain, and the disturbance of the long silent caves triggered an automated alert, one which has been heard. And answered.

Erik Cain and his Marines grimly take to the field once again, for what may be their final battle, against the robotic legions of the genocidal First Imperium. But facing a ruthless and technologically superior enemy may be easier than learning to fight alongside old enemies.

The First Imperium is book four of Jay Allan’s bestselling Crimson Worlds series (over 800,000 sold).

The Line Must Hold: Crimson Worlds 5
by Jay Allan
4.4 Stars (181 Reviews)
Genre: Science Fiction & Fantasy | Science Fiction

Darkness has come.

The robotic legions of the First Imperium burst into human space, destroying everything in their path. Their antimatter-powered fleets drove back the desperately defending human forces, seizing world after world. Directed by the maniacal Regent, the enemy pressed forward with one goal – the destruction of mankind.

The Superpowers of Earth, bitter enemies for over a century, have at last banded together to face the threat from outside. Their combined forces have fought stubborn delaying actions to buy time, but they haven’t managed to stop the relentless onslaught. Now the Rim has fallen, and the heart of human space lies before the seemingly unstoppable invaders.

On three worlds, mankind will make its stand, and all the power Earth and its colonies can muster has been gathered there. Three worlds – Sandoval, Garrison, Samvar. The Line.

Erik Cain grimly leads his veteran Marines and their new allies to Sandoval, to fight and to hold that world against anything the enemy throws at it. But Cain plans more than just a defense; he intends to annihilate the enemy forces… and he’ll sacrifice anything to win the ultimate victory. Even his soul.
The Line Must Hold is book five of Jay Allan’s bestselling Crimson Worlds series (over 800,000 sold).
