Big, bold military science fiction action from one of the genre’s biggest names.

New York Times bestselling author Ian Douglas's virtuosic Star Corpsman series proves one thing: The Marines are still the toughest sons of guns in the galaxy. As Bravo Company defuses a hostage crisis on an orbiting mining station, Navy Corpsman Elliot "Doc" Carlyle not only saves the lives of a wounded Marine and two extraterrestrial friendlies—he averts a terrorist strike intended to kill billions. His reward? Deployment on a recon mission into the darkest depths known to man. Abyss Deep is a foreboding ocean planet torn by extremes: boiling storm world on one side, unbroken glacier on the other. Humans established a research colony there to study the planet's giant sea serpents—but the colony has gone ominously silent. When Carlyle's team arrives, they discover a vessel belonging to a warlike alien species hovering above the atmosphere. But below the ice lurks a mystery so chilling it will make even Elliot Carlyle's blood run cold.

In the first novel in New York Times bestselling author Ian Douglas’ Solar Warden series, government conspiracy theories, UFO history, and thrilling space combat come together in an unforgettable interstellar military science fiction adventure. THE TRUTH HAS ALWAYS BEEN HERE In the final days of World War II, the Allies ransacked Berlin. Third Reich scientists were highly sought- out prizes for Americans and Russians desperate to possess the Nazi knowledge of nuclear firepower. But they failed to capture one of the most vital members of Adolf Hitler’s inner circle: SS Obergruppenfuhrer Hans Kammler. One of the engineers of Auschwitz, Kammler was also a liaison with the Nazis’ silent partners whose technological wonders nearly helped the Axis win the war—the alien species the Germans called the Eidechse. More than seven decades later, U. S. Navy SEAL Lieutenant Commander Mark Hunter has witnessed the impossible. On a mission in North Korea, an unidentified flying object destroyed a compound developing weapons of mass destruction. Now, he has been recruited to join a government agency that has been harboring a secret alliance with extraterrestrials since 1947. Selected to lead an elite force of soldiers, Hunter will travel across the stars to help humanity stake its claim among greater intelligent life in the universe. But the aliens who have infiltrated Earth and guided war mongering nations since the twentieth century have their own agendas…

But just as the Marines root out the last violent dissenters, an alien ship of unknown origin suddenly flees Earth's orbit. Is it mere coincidence . . . or a terrifying omen? President Alexander Koenig watches with great interest as USNA forces chase the runaways down. But upon first contact, it's not apparent where—or when—the crew is headed. For this bizarre species has somehow mastered the power to manipulate time itself. Now Koenig must decide whether he's dealing with angels of astonishing technological prowess . . . or the agents of humanity's destruction.

In the future, earth's warriors have conquered the heavens. 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.

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!
