Artificial Intelligence is our last hope of saving the war-ravaged Earth in this near future science fiction thriller from the apocalyptic mind of New York Timesbestselling author Nicholas Sansbury Smith (Hell Divers, The Extinction Cycle, Orbs).

The most advanced soldiers in human history are about to become obsolete.

Engines. Genetically modified warriors that keep the great Nova Alliance war machine churning against the enemy Coalition. Most days, Engines are all that stand between salvation and chaos. Led by legendary Engine, Captain Akira
Hayashi, Shadow Squad has fought on the frontlines for a decade. They are on the brink of victory when the Coalition launches a series of desperate and devastating attacks that cripple the Nova Alliance restoration sites vital to save the dying planet.

As the sites burn and Earth’s hope of salvation fades, Shadow Squad is equipped with neural implants to connect them to Apeiron, the first hybridhuman-AI entity. She is coded for what Captain Hayashi believes is an impossible
task–peace. But war isn’t the only threat to the Earth. Apeiron has uncovered a deadly secret with implications that could end all life. This rapidly approaching threat can be stopped only if humanity bands together on what will become
known as E-Day, a pivotal moment that will determine the evolution–or the extinction–of the entire human race.

The war started and ended in a day.
The machines won.
Now the fight for survival begins …

E-Day: The moment the machines evolved and humans nearly went extinct. In the chaos, one million people escaped Earth and fled to a secret colony on the dark side of the Moon. Deep beneath the lunar surface, in the cold, they wait for the inevitable–a second attack that will wipe humanity out forever.

Sergeant Tadhg Walsh is tired of waiting. He wants to fight back and return to Earth to search for Shadow Squad. But he has new orders from the Lunar Defense Corps: protect the colonies at all costs and forget about any survivors back home.

Captain Akira Hayashi is one of those survivors, forced to heal from his injuries in a submarine while the planet burns. Shadow Squad won’t be hiding for long, but before they can don their armor again, they must find a safe haven to plan their attack. When they locate a research station in the Mariana Trench, their sub heads into the depths. What they
find in the darkness changes everything they know about E-Day.

On the Moon, the LDC will do everything in its power to keep the truth about survivors on Earth a secret, even if it means sacrificing the few for the many. On Earth, Shadow Squad will have to make tenuous alliances with old enemies to stand a chance against the enemy. If they can unite, they might just have a chance of stopping the machines from wiping out
humanity on Earth and the Moon.

The final battle for humanity is about to begin …

On the moon, Ronin Hayashi trains to protect the colonies from the inevitable invasion of the machines. While he prepares to stand his ground, Sergeant Tadhg Walsh is planning an escape mission to deliver a weapon to the resistance on Earth.

At Neptune Station, Captain Akira Hayashi and Shadow Squad have returned from a deadly journey into enemy territory where they learn the machines are building an army at an astonishing rate. After continued attempts to contact the Lunar
Defense Corps for help, Shadow Squad accepts the hard truth–the LDC isn’t coming.

With hope for salvation dwindling, Akira deploys on a desperate mission to find Apeiron, believing only she can stop Doctor Otto Cross from completing his reset of Earth. But Akira soon realizes they need more than just Apeiron. Shadow Squad
must somehow reunite with Tadhg and the weapon he carries. Only then can Akira lead the charge against the machines in one last fight for the future of humanity.

A new monster emerges …

Newly christened as the leader of Delta Force Team Ghost, Master Sergeant Joe Fitzpatrick arrives in Normandy over seventy years after Allied Forces joined the fight against the Nazis. The war to free survivors and eradicate pockets of adult Variants and their offspring is underway by the European Unified Forces. But as the troops push east, rumors of a new type of monster spread through the ranks. Fitz and his new team quickly realize that the fight for Europe might be harder than anyone ever imagined.

They thought the war for America was over, but the war, for some, has just begun …

Back in the States, Captain Reed Beckham and Dr. Kate Lovato are settling into a new life on Plum Island. Across the United States, the adult Variants have all been wiped out, and the juveniles are on the run. But survivors soon realize there are other monsters at home, and they may be human.

On the eve of extinction all seems to be lost, but there is still one final hope …

Operation Liberty has failed. Humans are losing the war. With no other option, General Kennor decides to pull back the troops and give science a second chance.

Trapped in the extensive sewer system beneath New York, Master Sergeant Reed Beckham and the survivors of 1st Platoon must battle through the tunnels–where they make a grisly discovery in their attempt to escape.

At Plum Island, Dr. Kate Lovato is working on a new bioweapon to destroy the Variants. But when a derelict Navy destroyer crashes into the Connecticut shoreline, she is forced to deal with a nightmare she thought had ended.

As the doomsday clock ticks down and military bases fall across the country, the human race enters the age of extinction. Will science prevail–or will mankind vanish off the face of the planet?

A bioweapon designed to save the world …A scientific discovery that will alter human history …And a new threat that will bring humanity to the Edge of Exctinction.

The dust from Dr. Kate Lovato’s bioweapon has settled. Projections put death counts in the billions. Her weapon was supposed to be the endgame, but it turned a small percentage of those infected with the Hemorrhage Virus into something even worse.

Survivors call them Variants. Irreversible epigenetic changes have transformed them into predators unlike any the human race has ever seen. And they are evolving.

With the doomsday clock ticking, the fractured military plans Operation Liberty—a desperate mission designed to take back the cities and destroy the Variant threat. Master Sergeant Reed Beckham agrees to lead a strike team into New York City, but first he must return to Fort Bragg to search for the only family he has left.

At Plum Island, Kate discovers Central Command may have considerably underestimated the Variant population in New York. As Operation Liberty draws closer, Kate warns Beckham that Team Ghost won’t just face their deadliest adversary yet—they may be heading into a trap.

Hope rises in the hearts of those still left standing, but safety seems to be just an illusion. In a single night of shattering terror, Plum Island is destroyed, and key scientist Dr. Kate Lovato is abducted.

The end has arrived …

Almost seven weeks have passed since the Hemorrhage Virus ravaged the world. The remnants of the United States military have regrouped and relocated Central Command to the George Washington Carrier Strike Group. It’s here, in the North Atlantic, that President Jan Ringgold and Vice President George Johnson prepare to deploy a new bioweapon and embark on the final mission to take back the country from the Variants.

With his home gone and his friends kidnapped, Master Sergeant Reed Beckham and his remaining men must take drastic measures to save what’s left of the human race. But not everyone at Central Command has the same plan for victory. As the Variants continue to evolve, only a handful of heroes stand between the creatures and mankind’s total extinction.

One way or another, the battle for the United States of America ends here.

There’s a storm on the horizon …

Central Command is gone, the military is fractured, and the surviving members of Team Ghost, led by Master Sergeant Reed Beckham, have been pushed to the breaking point. While the strong return to the battlefield, the wounded are forced to stay behind on Plum Island and fight their inner demons.

Betrayed by the country they swore to defend and surrounded by enemies on all sides, Team Ghost has one mission left: protect Dr. Kate Lovato and Dr. Pat Ellis while they develop a weapon to defeat the Variants once and for all. But after a grisly discovery in Atlanta, Kate and Ellis realize their weapon might not be able to stop the evolution of the monsters.

Joined by unexpected allies and facing a new threat none of them saw coming, the survivors are running out of time to save the human race from extinction.

The worst of nature and the worst of science will bring the human race to the brink of extinction.

Master Sergeant Reed Beckham has led his Delta Force Team, codenamed Ghost, through every kind of hell imaginable and never lost a man. When a top secret Medical Corps research facility goes dark, Team Ghost is called in to face their deadliest enemy yet–a variant strain of Ebola that turns men into monsters.

After barely escaping with his life, Beckham returns to Fort Bragg in the midst of a new type of war. The virus is already spreading. As cities fall, Team Ghost is ordered to keep CDC virologist Dr. Kate Lovato alive long enough to find a cure. What she uncovers will change everything.

Total extinction is just on the horizon, but will the cure be worse than the virus?

“Extinction Lost” is a short story that should be read after book 6, Extinction Aftermath. NOTE: This story was originally published in SNAFU: Black Ops.

The war continues …

Two days after the events of Extinction Aftermath, European Unified Command calls on Team Ghost for a top secret mission. The residents of a small Inuit fishing village in Greenland have gone missing and reports of Variants unaffected by Kryptonite have surfaced.

Fatigued, injured, and unaware of the events back in the United States, Master Sergeant Joe Fitzpatrick leads Team Ghost into the remote and alien winter landscape to determine the fate of the missing villagers. But as the operation unfolds they discover a harrowing revelation that could impact the world war against the Variants, and the future of the human race.

A year has passed since the Hell Divers defeated the machines at Kilimanjaro. The freed captives have settled into their new home at the Vanguard Islands, joining survivors from around the world.

At the end of the world, who will survive?

The year is 2061, and the planet is dying. Cataclysmic solar storms have forced leaders from around the world to finally put aside their differences and agree on one thing–to jump ship. The human race is headed to Mars.

Dr. Sophie Winston is hired by New Tech Corporation to test a biosphere deep within the heart of Cheyenne Mountain; a mission she believes will help prepare the company for the three-year flight to the red planet. But, just days into the assignment, things start to go wrong. When the blast doors hiss open, Winston’s team finds a changed world outside. Humans are gone, vanished without a trace, and they aren’t the only thing missing. The planet’s water has disappeared, too.

As the team explores their surroundings, they find thousands of luminous blue orbs lining the streets. It isn’t until they uncover what’s inside that they realize the nightmare that lies ahead.

At the end of the world, who can you trust?

The aliens have invaded, wiping out almost all life on Earth. Their goal: water. Huge spaceships are draining the oceans, and the few remaining humans have been herded into farms, where their bodies are harvested to support the growing alien army.

Humanity’s last chance lies in the biospheres that have been planted secretly across the globe. But all is not peaceful in the biome led by Dr. Sophie Winston. With resources dwindling and tensions high, her small group of survivors is divided. Some want to fight, some want to stay hidden, and Sophie just wants to keep everyone alive.

When one of their own, eleven-year-old Jeff, is kidnapped by the Organics, Sophie is forced to pick sides. With the help of a promising new magnetic weapon, the biosphere team just might have a fighting chance to save Jeff and the world–if they live long enough to use it.

At the end of the world, who do you save?

With their numbers diminishing and the alien armies growing stronger, Sophie’s biosphere decides to join forces with the team from NTC’s submarine.

Using data from a surviving satellite, they discover strange, alien poles at each of the world’s seven highest summits: alien technology that the survivors believe may hold the key to shutting down the alien ships once and for all.

That’s not all. The satellite also discovers an encrypted set of coordinates that reveal SOS messages from US Military bases around the world, all activated on invasion day, except for one: Offutt Air Force Base.

But before they can launch an offensive, the biosphere team must deal with sabotage from within and a strange nanotechnology that has infected several of the survivors. As tensions rise, Sophie and team must decide whether a new discovery at Offutt is worth abandoning the biosphere. The more the team learns, the more they realize the planet may be beyond saving and that salvation may require leaving the planet forever.

At the end of the world, who will escape?

Operation Redemption, the final desperate mission in taking back the planet from the Organics has failed. Captain Rick Noble and his soldiers have been captured and imprisoned on an alien ship. But not all is lost. Their sacrifice allowed Doctor Sophie Winston, Doctor Emanuel Rodriguez, and their small team to escape in the NTC Sunspot–their destination, Mars. The perilous journey to find a lost human colony may offer Sophie and the rest of humanity a chance at life.

Those left on Earth are caught in a life-and-death struggle. Corporal Athena Rollins of the NTC Ghosts of Atlantis submarine still believes they can beat the aliens with the help of AI Alexia, but time is running out. The oceans are draining, the temperatures are rising, and the other pockets of survivors are perishing every day.

Trapped on the Organic ship, Captain Rick Noble is desperate to escape and save his crew back on Earth. As he waits for his opportunity he finds an ally in the most unlikely of places.

The fight for Earth may be lost, but the fight for Mars and the future of the human race may have just begun …

In the year 2055, scientists discover something far worse than rising temperatures and rising seas–they discover massive sunspots that are producing unprecedented solar flares.

With little time to prepare for the storms, NASA recruits doctors Sophie Winston and Emanuel Rodriguez to help monitor the solar weather. At first, the duo believes they have been hired for a routine project. But when arriving at the Johnson Space Center they quickly realize they haven’t been told everything about their mission. And as a massive storm races toward Earth, they begin to suspect that it isn’t a natural event. Millions of miles away something is feeding the storms …

Across the world, the United States recalls troops to combat civil unrest after the biggest economic meltdown in history. Marine Sergeant Ronaldo Salvatore’s platoon comes home to a powder keg that could ignite a civil war.

While some see the coming collapse as the end, others see opportunity. Fleeing Naples after rival crime lords decimated his family, Don Antonio Moretti settles in Los Angeles to rebuild his criminal empire. But he is far from alone in his ambitions–the cartel and rival gangs all want the same turf, and they will sacrifice their own soldiers and the blood of innocents to get it.

As open warfare erupts across the states, Salvatore fights his way back to LA, where his son has joined the police in the battle for a city spiraling into anarchy. Family is everything, and the Morettis and Salvatores will do what they must to protect their own. But how far will they go to survive in a new economy where the only currency is violence?

The civil war is over, but the struggle for power is just beginning …

In the aftermath of a devastating civil war, America has fallen into anarchy and chaos. Los Angeles is divided into different territories controlled by criminal organizations. Don Antonio Moretti has won a slice of the pie but is hungry for more. In his quest for power, he sends his nephew and a small crew to Mexico, to negotiate a new deal for their staple product, while the don returns to Italy for some unfinished business.

While the crime families battle for power in LA, Dominic Salvatore and his elite team at the LAPD fight tirelessly to stem the rot. But their fight often seems futile in a force rife with corruption. Dom’s father, Ronaldo, is a deputy fighting to secure the border, but when intel arises about his missing daughter, he leaves Los Angeles for the desert wastes, to find her and bring her home.

To the Morettis and the Salvatores, family is everything, and they will protect their own no matter the cost.

To fight evil, you must embrace evil.

The motto of Marine Sergeant Ronaldo Salvatore lives on in his son, Dominic, and his undercover team known as the Saints. With the support of LAPD Captain Zed Marks, the Saints embark on a mission to destroy the criminal organizations that have a stranglehold on Los Angeles.

Through brains, cunning, and sheer ruthlessness, the most powerful leader, Don Antonio Moretti, has risen from underdog to contender for the throne. He believes that only the Vega family of narcos stands in his way, but he has underestimated another underdog.

As the Morettis and Vegas slug it out, the Saints go outside the law to deliver the City of Angels from evil. In this three-way death match, the streets will run with blood before a victor ever emerges.
