Scientists have discovered something astonishing in the subterranean ruins of a sprawling Martian city: startling evidence of an alternative history that threatens to split humanity into opposing factions and plunge the Earth into chaos and war. The USMC -- a branch of a military considered, until just recently, to be obsolete -- has dispatched the Marine Mars Expeditionary Force, a thirty-man weapons platoon, to the Red Planet to protect American civilians and interest with lethal force if necessary.

Because great powers are willing to devastate a world in order to keep an ancient secret buried. Because something that was hidden in the Martian dust for half a million years has just been unearthed . . . something that calls into question every belief that forms the delicate foundation of civilization . . .

Something inexplicably human.

But Mars is not the sole repository of alien wonders. The Earth's moon hides unsettling mysteries of its own-and dangerous secrets pointing toward an unstoppable threat advancing from somewhere beyond the solar system. And as scientists on both sides ract to utilize technology they have only barely begun to comprehend, the UN makes the opening move in a gambit that could end the hostilities quickly and decisively by bringing about the death of millions...without the aid of alien-inspired weaponry.

A bad situation worsens by the nanosecond. And that means it's time to call in the Marines -- to make a life or death stand on the gray shores of Luna.

But on a distant world,
Humanity is in chains ...

Many millennia ago, the human race was enslaved by the An -- a fearsome alien people whose cruel empire once spanned the galaxies, until they were defeated and consigned to oblivion. But a research mission to the planet Ishtar has made a terrifying -- and fatal -- discovery: the Ahanu, ancestors of the former masters, live on, far from the reach of Earth weapons and technology ... and tens of thousands of captive human souls still bow to their iron will. Now Earth's Interstellar Marine Expeditionary Unit must undertake a rescue operation as improbable as it is essential to humankind's future, embarking on a ten-year voyage to a hostile world to face an entrenched enemy driven by dreams of past glory and intent once more on domination. For those who, for countless generations, have known nothing but toil and subjugation must be granted, at all costs, the precious gift entitled to all of their star-traveling kind: freedom!

2042: In the gray dust of the Earth's Moon, an extinct enslaving race left behind more answers, more questions...and a grim warning.

2067: As Earth's warring factions clash in space for scraps of alien technology, a strange artifact lies trapped beneath the ice-locked oceans of Europa: a machine that holds the key to the final human destiny.

It is called "The Singer" for the eerie tone it emits. An artificial intelligence built eons ago, it may ultimately solve the mystery of the vanished alien races responsible for the birth and development of humanity. But after decades of war, the hostile nations of Earth care more for power than for knowledge. And now all that stands between the coveted Al and an all-out Chinese assault is a vastly outnumbered contingent of U.S. marines, dug in beneath the baleful red eye of Jupiter. As terrifying events light years distant begin to converge---with confrontation imminent and annihilation inevitable---a secret history of creation and doom must at long last be contended with...if humankind is to finally claim its glorious heritage among the stars.2040: Ruins of ancient civilization uncovered on Mars reveal startling truths about the creation of humankind.

Planet by planet, galaxy by galaxy, the inhabited universe has fallen to the alien Xul.

Now only one obstacle stands between them and total domination: the warriors of a resilient race the world-devourers nearly annihilated centuries ago . . .

A power vast, ancient, and terrifying, the mighty Xul have lost track of the insignificant humans hundreds of years after devastating their home world—which has enabled the United Star Marines to operate unnoticed and unhindered. A near-autonomous intergalactic policing force, they battle in defense of an Earth they may not live to see again. Now, following the trail of a vanished twenty-fourth-century transport, they are journeying through an unexplored stargate to the edge of an unknown galaxy many light years from their sun. For the last, best, and only chance to defeat the tyrants of the universe may at long last be at hand . . .

The Marines are heading into the perilous unknown . . . and what transpires there could reshape the universe for millennia to come.

With the planet's fighting men and women deployed across the galaxy—battling in the noble cause of enslaved humanity—the insidious Xul have reached across space to devastate the unsuspecting Earth with asteroid fire. Without warning, a once majestic world is reduced to near-rubble—and the very future of humankind is in dire jeopardy.

Interplanetary leaders are on the brink of abandoning Earth and its colonies to an overwhelming enemy. But Brigadier General Garroway of the Marine Interstellar Expeditionary Unit is unwilling to concede defeat—not as long as there's a single marine willing to give his or her life in defense of their embattled homeworld. The ultimate battle is about to be waged—with breathtaking new attack technology, an ancient code of courage, and the help of an ally race that once inhabited the Earth—in a war that will alter the universe forever . . .

War is forever

The people on Earth no longer remember how the human race was nearly obliterated centuries earlier during the terror visited upon them by the merciless Xul. But the Star Marines, thirty thousand light years from home, know all too well the horror that still lives.

In the year 2886, in the midst of the intergalactic war that has been raging nonstop for nearly a decade, the unthinkable has occurred. Intelligence has located the gargantuan hidden homeworld of humankind's dedicated foe, the brutal, unstoppable Xul. The time has come for the courageous men and women of the 1st Marine Interstellar Expeditionary Force to strike the killing blow. But misguided politics on an Earth that no longer supports their mission could prove the Marine's greatest enemy—as they plunge bravely into the maelstrom of conflict . . . and into the heart of a million-year-old mystery.

Chaos has erupted throughout the known galaxy, threatening countless colonies and orbital habitats—as the Associative struggles vainly to keep the peace. Extreme measures are called for in these times of dire crisis, and the Star Marines are awakened from their voluntary 850-year cybe-hibe sleep. But General Trevor Garroway and his warriors are about to discover that the old rules of engagement have drastically changed . . .

The end begins with an old-style assault on rebels at the Tarantula Stargate. But true terror looms at the edges of known reality. Humankind's eternal enemy—the brutal, unstoppable Xul—approaches, wielding a weapon monstrous beyond imagining. Suddenly not only is the future in jeopardy, but the past is as well—and if the Marines fail to eliminate their relentless xenophobic foe once and for all, the Great Annihilator will obliterate every last trace of human existence.

The first book in the epic saga of humankind's war of transcendence

There is a milestone in the evolution of every sentient race, a Tech Singularity Event, when the species achieves transcendence through its technological advances. Now the creatures known as humans are near this momentous turning point.

But an armed threat is approaching from deepest space, determined to prevent humankind from crossing over that boundary—by total annihilation if necessary.

To the Sh'daar, the driving technologies of transcendent change are anathema and must be obliterated from the universe—along with those who would employ them. As their great warships destroy everything in their path en route to the Sol system, the human Confederation government falls into dangerous disarray. There is but one hope, and it rests with a rogue Navy Admiral, commander of the kilometer-long star carrier America, as he leads his courageous fighters deep into enemy space towards humankind's greatest conflict—and quite possibly its last.
