It's 2524. Harvest is a peaceful, prosperous farming colony on the very edge of human-controlled space. But humanity has unknowingly trespassed on holy ground - straying into the path of the aggressive, theocratic empire known as the Covenant. What begins as a chance encounter between an alien privateer and a human freighter soon catapults all of mankind into a struggle for its very existence. But humanity is also currently locked in a bitter civil war of its own: the Insurrection. 

The 26th century. Once considered clandestine, the Spartan-II program has now gone public. Tales of armored supersoldiers fending off thousands of Covenant attacks have become the stuff of legend. While the Master Chief defends a besieged Earth and the myriad factions of the Covenant continue their crusade to eliminate humanity, an ultra-secret cell of the Office of Naval Intelligence known as “Section Three” devises a plan to buy the UNSC vital time. It will need hundreds of willing soldiers, though - and one more Spartan - to get the job done. 

When humanity expanded beyond the safety of Earth to new stars and horizons, it never dreamed what dangers would be encounter there. When the theocratic alien juggernaut known as the Covenant declared war upon the fragile human empire, millions of lives were lost - but millions of heroes also rose to the challenge. This collection of 11 stories dives into the depths of the vast Halo universe, not only from the perspective of those who fought and died to save humanity, but also from those who vowed to wipe it out of existence.

It's 2552. The theocratic military alliance known as the Covenant is showing no mercy as it continues to assault every human world it encounters, but in the way lies humanity’s greatest champion, the supersoldier Spartan John-117 - the Master Chief. Together with his AI companion Cortana and the last remaining Spartans, the galaxy-spanning fight rages on two fronts following the destruction of the human military stronghold Reach by Covenant forces and the mysterious artificial ringworld known as “Halo” at the hands of the Master Chief. 

One hundred thousand years ago, the galaxy was populated by a great variety of beings. But one species - eons beyond all others in both technology and knowledge - achieved dominance. They ruled in peace but met opposition with quick and brutal effectiveness. They were the Forerunners - the keepers of the Mantle of Responsibility, the next stage of life in the Universe’s Living Time. And then they vanished. This is their story.

It's 2552. Having barely escaped the final battle for Reach against the vast alien alliance known as the Covenant, the crew of the Pillar of Autumn, including Spartan John-117 - the Master Chief - and his AI companion Cortana, is forced to make a desperate escape into slipspace. But their destination brings them to an ancient mystery and an even greater struggle. 

It's 2553. Welcome to humanity’s new war: silent, high-stakes, and unseen. This is a life-or-death mission for the Office of Naval Intelligence’s black-ops team, Kilo-Five, which is tasked with preventing the ruthless Sangheili, once the military leaders of the alien alliance known as the Covenant, from regrouping and threatening humankind again. What began as a routine dirty-tricks operation - keeping the Sangheili occupied with their own insurrection - turns into a desperate bid to extract one member of Kilo-Five from the seething heart of a brutal civil war.  

Broken Circle will explore an Elite splinter group rebelling against the Covenant in its earliest days, a brave Prophet caught in the machinations of the new Covenant leadership, and the root of the betrayal that would ultimately shatter the Covenant during events seen in the blockbuster Xbox video game Halo 2.

In the company of a young girl and an old man, Chakas begins an epic journey across a lost and damaged Halo ringworld in search of a way home, an explanation for the warrior spirits rising up within, and the reason for the Forerunner Librarian’s tampering with human destiny.  

It's 2553. With the 30-year-long Covenant War finally over, the Office of Naval Intelligence faces old grievances rising again to threaten Earth. Angry and bitter colonists - still wanting to settle scores from an insurrection put on hold for three decades - crave justice...as does a man whose life was torn apart by ONI when his young daughter was abducted for the SPARTAN-II program.  

While Spartans get all the glory, no soldier - not even the legendary Master Chief - wins a war on his own. Gunnery Sergeant Edward Buck and his team of Orbital Drop Shock Troopers (ODSTs) played a major role in saving the Earth from all-out invasion at the end of the Covenant War - acts of bravery and ingenuity that did not go unnoticed by the United Nations Space Command.

One hundred thousand years ago, Chaos rules the final days of the Forerunner empire. The Flood - a horrifying, shape-changing, and unstoppable parasite - has arrived in force, aided by unexpected allies, and internal strife has desperately weakened Forerunner defenses.  

It is 2555, more than two years after the Master Chief went missing in action following a decisive conflict on Installation 00 - the massive, extragalactic Forerunner construct known as the Ark - as part of the final chapter in humanity's bloody 30-year struggle against the overwhelming forces of the Covenant.

It's 2526. It has been almost a year since humanity engaged in its destructive first contact with a theocratic military alliance of alien races known as the Covenant. Now, the hostilities have led to open war, and the United Nations Space Command understands virtually nothing about its new enemy. The UNSC’s only hope lies with the Spartans: enhanced super-soldiers trained from childhood via a clandestine black-ops project to be living weapons. But not everyone wants the Spartans to succeed. 

2526. It has been more than a year since humanity first encountered the hostile military alliance of alien races known as the Covenant, and several weeks after the United Nations Space Command’s devastating counterattack of Operation: SILENT STORM was deemed an overwhelming success. The UNSC has put its faith in the hands of the Spartans, led by the legendary Master Chief, John-117: enhanced super-soldiers raised and trained from childhood via a clandestine black ops project to be living weapons.
