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.

New York Times best-selling military science fiction author Ian Douglas brings us the eighth - and penultimate - Star Carrier novel, Bright Light, combining the best action, adventure, and hard science into this universe-spanning series. There’s no more time.... There’s always more time.... Trevor Gray has been stripped of his command of the starship America and is unsure what to do with his life. Having dedicated so much of himself to the service, he knew following the super-AI Konstantin’s advice could have severe consequences. He just never thought he would be out of the fight. Because that’s what Earth is in: a fight against a sinister alien force that is so technologically advanced, there seems to be little hope. That’s why he had disobeyed his orders in the first place: to figure out a way to stop them. But now he’s beached. Which is just what Konstantin wanted. For the super-AI has a plan: connect Gray with the Pan-Europeans and set him on a course to the remote star Deneb. There, he is to make contact with a mysterious alien civilization using the new artificial intelligence Bright Light, and maybe - if they can make it in time - prevent humanity from being wiped from the universe.

The Year is 2040. The Marines have landed on Mars to guard the unearthed secrets of an ancient and dangerous alien race: Ourselves. 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.

The Truth Has Always Been Here.... In the final days of World War II, the Allies ransacked Berlin.

More than seven decades later, US Navy SEAL Lieutenant Commander Mark Hunter has witnessed the impossible.

The revelations on Mars - a half-million year-old legacy of the vanished star-traveling Builders - have fed the flames of catastrophic war. A beleaguered United States and its Russian and Japanese allies struggle to hold their own against the indomitable forces of the enemy United Nations. The bloody conflict that has swept over the home planet now rages across the blackness of space - with the U.S. Marine Corps in the vanguard, leading the charge as always. 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 race 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.
