Devastated by World War III, then an alien invasion coupled with "Danse Macabre", a deadly virus attack, Earth is almost completely depopulated. The land is devastated. The sky is dark with nuclear winter. Despite the swarm's invasion ultimately being defeated, billions of humans were taken on board the Battle Core, infecting it and then wiped out when it plunged into the sun to prevent further infecting the swarm. 

Mike Turcotte, the Special Forces officer who led the fight against the Airlia, which ruled our planet from the shadows for over 10 millennia, has returned to Area 51. Earth has freed itself from the shackles of alien domination but at high cost while winning World War III. He has learned what he believes is the truth about human origins. A truth so devastating he insists it cannot be made public.

Dr. Lisa Duncan and Special Forces officer Mike Turcotte know better than anyone that no secret is safe for long - especially one that offers untold power. Case in point: No sooner does Turcotte’s elite Area 51 team uncover a dormant alien ship in Earth's orbit than a group of alien-human hybrids seizes it and uses its technology to commandeer a satellite array bristling with nuclear missiles. Now they’re demanding that humankind hand over the key to an ancient stash of alien technology…or watch an entire continent be reduced to atomic rubble.

Many millennia ago, humans, including us, were seeded on 15 worlds by an alien race, the Airlia. We believe we evolved, but the reality is we were bred as cannon fodder for the Airlia’s interstellar war against the Swarm, a viral race whose only mission appears to be the obliteration of sentient life wherever encountered. On some worlds humans realized the truth about their origins, uncovered their hidden alien overlords, and rebelled.

Staff Sergeant Winthrop Carter only enlisted in the army for the steady pay. When he cheated on the Special Forces’ final exam, he never expected his actions would get him drafted into the Nightstalkers - an elite team with a mysterious mission and even more mysterious leader. For decades, Rifts have been opening and unleashing bloodthirsty alien life forms into our reality. The Nightstalkers’ goal is to shut down these breaches and stop the beings that emerge from rampaging out of control.

Mythological artifacts become a modern arsenal in a millennia-long interstellar battle. On one side stands the alien race that styled itself as gods to secretly steer human evolution. On the other is an elite team of Area 51 commandos, dedicated to freeing humanity from their interstellar overlords. Special Forces officer Mike Turcotte and his former lover Lisa Duncan are among the few who know the truth about the extraterrestrial threat - and have the power to fight it.

In his time at Area 51, Mike Turcotte has learned one thing: We are not alone. As part of an elite Special Forces team, the former Green Beret has encountered things that are well beyond human understanding. Now, two ancient rivals from another world are vying to dominate Earth, and Mike and his team must choose which army to side with. The key to averting the crisis lies in a single weapon: Excalibur. The mythical, legendary sword of King Arthur is real and can unlock a galactic power beyond what anyone - human or alien - has ever seen. And Mike must keep it from falling into the wrong hands.

Special Forces officer Mike Turcotte has paid his dues in battle and in blood. Now assigned to Area 51, he fights the toughest enemy of his career: the alien race who arrived on Earth millennia ago and have returned to claim the planet. Mike has dodged bullets and faced weapons of mass destruction to give humanity another day of reprieve. But when his lover, scientist Lisa Duncan, falls into evil hands, Mike must decide which prize means the most to him - the woman he loves or the legendary Grail.

Hidden deep in the Amazon rain forest is a place shrouded in mystery. It is called The Mission. And in nearby villages people are screaming in pain as they die from a virus more deadly than Ebola. They can't escape it. They can't cure it. They can't stop it from exploding into a worldwide epidemic poised to kill us all.... Scientist Lisa Duncan and Special Forces Officer Mike Turcotte suspect this new "Black Death" is actually a biological weapon in an escalating war between us...and "them".

When scientist Lisa Duncan and Special Forces officer Mike Turcotte uncovered the stunning truth about Area 51--a "training area" on Nellis Air Force Base in Nevada--they opened up a Pandora's box kept hidden from the American public for 50 years.
