Retribution

by Troy Denning

Published 29 August 2017
December 2553. Less than a year after the end of the Covenant War, a string of violent incidents continues to threaten the tenuous peace in human-held space, culminating in the assassination of UNSC fleet admiral Graselyn Tuwa and the abduction of her family. It is a provocation so outrageous that the Office of Naval Intelligence must retaliate swiftly and ferociously--but only after its operatives identify her killer and rescue the hostages. This mission will be the first for homicide-detective-turned-ONI-operative Veta Lopis and her young team of Spartan-IIIs, and some­thing feels wrong from the start. The obvious suspect is an infamous Brute dokab who leads the Keepers of the One Freedom, a Covenant splinter group in fierce opposition to the UNSC. But Lopis and her team soon realize that the truth is much more insidious than they could ever have imagined, and along with Fred-104, Kelly-087, and Linda-058 of Blue Team for combat support, must stop a plan hatched in the bowels of the secret research station Argent Moon--a plan so sinister it could destroy all those still reeling from thirty years of inter­galactic conflict....

Legacy of Onyx

by Matt Forbeck

Published 14 November 2017

An original full-length novel set in the Halo universe and based on the New York Times bestselling video game series!

Molly Patel was only seven years old when the alien alliance known as the Covenant destroyed her homeworld and killed her family. As one of the few to escape the glassing of Paris IV, and despite the United Nations Space Command winning the war on behalf of humanity, Molly never forgot how much she had lost.

Nine years later, when her adoptive parents—research scientists specializing in ancient Forerunner technology—are called to the mysterious and wondrous place known as Onyx, Molly vehemently objects. It’s not so much that Molly’s concerned about relocating to inside a spherical construct the diameter of an entire solar system, but the fact that she also has to live alongside members of the same alien species that murdered her family. And when the Servants of the Abiding Truth—a violent ex-Covenant sect under the guidance of the notorious Pale Blade—somehow makes its way inside this supposedly impregnable sphere, Molly is now forced to consider if she and her new parents have made a terrible and fatal mistake in coming here....

A secret mission enacted by the Office of Naval Intelligence could possibly help turn the tide, and has Buck reluctantly agreeing to reform his old team, Alpha-Nine.

Silent Storm

by Troy Denning

Published 1 September 2018
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. There are only two certainties--the Covenant is determined to eradicate humanity, and they have the superior technology to do just that. 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. Their designated commander, Petty Officer John-117, has been assigned to lead the Spartans on a desperate counterattack designed to rock the Covenant back on its heels, and to buy humanity the time it needs to gather intelligence and prepare its defenses.

Find. Claim. Profit. In a post-Covenant War galaxy littered with scrap, it's the salvager's motto-and Rion Forge certainly made her mark on the trade. All she wanted was to grow her business and continue the search for her long-lost father, but her recent discovery of a Forerunner debris field at the edge of human-occupied space has now put her squarely in the crosshairs of the Office of Naval Intelligence and the violent remains of the Covenant. Each faction has a desire to lay claim to the spoils of ancient technology, whatever the cost, sending Rion and the crew of the Ace of Spades on a perilous venture-one that unexpectedly leads them straight into danger far greater than anything they've ever encountered...

Oblivion

by Troy Denning

Published 24 September 2019

A Master Chief story and original full-length novel set in the Halo universe—based on the New York Times bestselling video game series!

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. But the Covenant—enraged and fearful of their enemy’s unexpected strategies and prowess—is not taking its recent defeat lightly, and is now fully determined to eradicate humanity from existence, brutally overrunning the ill-fated planets of the Outer Colonies faster than retreats can be ordered.

If the UNSC has any chance of stemming the tide of the war, the Master Chief and Blue Team must drop onto an empty, hellish world in order to capture a disabled Covenant frigate filled with valuable technology. It has all the makings of a trap, but the bait is far too tempting to ignore—and this tantalizing prize is being offered by a disgraced and vengeful Covenant fleetmaster, whose sole opportunity for redemption lies in extinguishing humanity’s only hope of survival…

October 2559. It has been a year since the renegade artificial intelligence Cortana issued a galaxy-wide ultimatum, subjecting many worlds to martial law under the indomitable grip of her Forerunner weapons. Outside her view, the members of Blue Team—John-117, the Master Chief; Fred-104; Kelly-087; and Linda-058—are assigned from the UNSC Infinity to make a covert insertion onto the ravaged planet Reach.

Their former home and training ground—and the site of humanity’s most cataclysmic military defeat near the end of the Covenant War—Reach still hides myriad secrets after all these years. Blue Team’s mission is to penetrate the rubble-filled depths of CASTLE Base and recover top-secret assets locked away in Dr. Catherine Halsey’s abandoned laboratory—assets which may prove to be humanity’s last hope against Cortana.

But Reach has been invaded by a powerful and ruthless alien faction, who have their own reasons for being there. Establishing themselves as a vicious occupying force on the devastated planet, this enemy will soon transform Blue Team’s simple retrieval operation into a full-blown crisis. And with the fate of the galaxy hanging in the balance, mission failure is not an option…

Epitaph

by Kelly Gay

Published 2 January 2024
An original novel set in the Halo universe—based on the New York Times bestselling video game series!

Stripped of armor, might, and memory, the legendary Forerunner warrior known as the Didact was torn from the physical world following his destructive confrontation with the Master Chief and sent reeling into the mysterious depths of a seemingly endless desert wasteland. This once powerful and terrifying figure is now a shadow of his former self—gaunt, broken, desiccated, and alone. But this wasteland is not as barren as it seems. A blue light glints from a thin spire in the far distance…

Thus begins the Didact’s great journey—the final fate of one of the galaxy’s most enigmatic and pivotal figures.

Halo: Glasslands

by Karen Traviss

Published 24 November 2009

The Covenant has collapsed after a long, brutal war that saw billions slaughtered on Earth and her colonies. For the first time in decades, however, peace finally seems possible. But though the fighting's stopped, the war is far from over: it's just gone underground. The UNSC's feared and secretive Office of Naval Intelligence recruits Kilo-Five, a team of ODSTs, a Spartan, and a diabolical AI to accelerate the Sangheili insurrection. Meanwhile, the Arbiter, the defector turned leader of a broken Covenant, struggles to stave off civil war among his divided people.

Across the galaxy, a woman thought to have died on Reach is actually very much alive. Chief scientist Dr. Catherine Halsey broke every law in the book to create the Spartans, and now she's broken some more to save them. Marooned with Chief Mendez and a Spartan team in a Forerunner slipspace bubble hidden in the destroyed planet Onyx, she finds that the shield world has been guarding an ancient secret - a treasure trove of Forerunner technology that will change everything for the UNSC and mankind.

As Kilo-Five joins the hunt for Halsey, humanity's violent past begins to catch up with all of them as disgruntled colony Venezia has been biding its time to strike at Earth, and its most dangerous terrorist has an old, painful link with both Halsey and Kilo-Five that will test everyone's loyalty to the limit.


Halo: The Thursday War

by Karen Traviss

Published 2 October 2012

WELCOME TO HUMANITY’S NEW WAR: SILENT, HIGH STAKES, AND UNSEEN.

This is a life-or-death mission for ONI's black-ops team, Kilo-Five, which is tasked with preventing the rutheless Elites, once the military leaders of the Covenant, from regrouping and threatening humankind again. What began as a routine dirty-tricks operation - keeping the Elites busy with their own insurrection - turns into a desperate bid to extract one member of Kilo-Five from the seething heart of an alien civil war.

But troubles never come singly for Kilo-Five. Colonial terrorism is once again surfacing on one of the worlds that survived the war against the Covenant, and the man behind it is much more than just a name to Spartan-010. Meanwhile, the treasure trove of Forerunner technology recovered from the shield world of Onyx is being put to work. And a kidnapped Elite plots vengeance on the humans he fears will bring his people to the brink of destruction.


Following the events of Halo 4, the UNSC Infinity is deployed to security detail for a peace summit between the Elites and Brutes. When the negotiations are ambushed by a mercenary fleet, Infinity is drawn into a plot which leads them to the discovery of a long-lost UNSC asset trapped behind enemy lines. This graphic novel collects the comics Halo: Escalation 1 through 6.
