The New York Times bestseller—part of the expanded universe based on the award-winning video game series Halo! The twenty-sixth century. Once considered clandestine, the Spartan-II program has now gone public. Tales of armored super-soldiers 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. The planet Onyx is virtually abandoned and the perfect place to set this new plan in motion. But when the Master Chief destroys Halo, something is triggered deep within Onyx: Ancient Forerunner technology stirs, and fleets of UNSC and Covenant vessels race to claim it and change the course of the Human-Covenant War. But this reawakened and ancient force may have plans of its own…

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.

But they soon discover that this enigmatic ringworld is much more than it seems. Built one hundred thousand years ago by a long-lost civilization known as the Forerunners, this “Halo” is worshipped by the Covenant—a sacred artifact they hope will complete their religious quest for supposed transcendence, and they will stop at nothing to control it. Engaging in fierce combat, Master Chief and Cortana will go deep into the Halo construct and uncover its dark secret and true purpose—even as a monstrous and far more vicious enemy than the Covenant emerges to threaten all sentient life on Halo and the galaxy beyond…
