Halo: Cryptum, the first novel in the Forerunner Saga trilogy by science fiction legend Greg Bear, is set in the Halo universe and based on the New York Times bestselling video game series! It is a tale of life, death, intergalactic horror, exile, and maturity...a story of overwhelming change, and of human origins; For the Mantle may not lie upon the shoulders of Forerunners forever. 100,000 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, the next stage of life in the Universe's Living Time. And then they vanished. This is their story. Bornstellar Makes Eternal Lasting is a young rebellious Forerunner. He is a Manipular, untried, yet to become part of the adult Forerunner society, where vast knowledge and duty waits. He comes from a family of Builders, the Forerunners' highest and most politically powerful rate. It is the Builders who create the grand technology that facilitates Forerunner dominance over the known universe. It is the Builders who believe they must shoulder the greatest burden of the Mantle, as shepherds and guardians of all life. Bornstellar is marked to become a great Builder just like his father. But this Manipular has other plans. He is obsessed with lost treasures of the past. His reckless passion to seek out the marvelous artifacts left behind by the Precursors, long-vanished superbeings of unknowable power and intent, forces his father's hand. Bornstellar is sent to live among the Miners, where he must come to terms with where his duty truly lies. But powerful forces are at play. Forerunner society is at a major crux. Past threats are once again proving relentless. Dire solutions, machines and strategies never before contemplated, are being called up, and fissures in Forerunner power are leading to chaos. On a Lifeworker's experimental planet, Bornstellar's rebellious course crosses the paths of two humans, and the long lifeline of a great military leader, thus forever changing Bornstellar's destiny ...and the fate of the entire galaxy.

The second in a new series of three HALO novels, Greg Bear's Halo: Primordium dives back into the Forerunner saga. A long time ago, I was a living, breathing human being. I went mad. I served my enemies. They became my only friends. Since then, I've traveled back and forth across this galaxy, and out to the spaces between galaxies—a greater reach than any human before me. You have asked me to tell you about that time. Since you are the last true Reclaimer, I must obey. Are you recording? Good. Because my memory is failing rapidly. I doubt I'll be able to finish the story. Once, on my birth-world, a world I knew as Erde-Tyrene, and which now is called Earth, my name was Chakas... In the wake of apparent self-destruction of the Forerunner empire, two humans—Chakas and Riser—are like flotsam washed up on very strange shores indeed. Captured by the Master Builder, misplaced during a furious battle in space, they now find themselves on an inverted world where horizons rise into the sky, and where humans of all kinds are trapped in a perilous cycle of horror and neglect. For they have become both research animals and strategic pawns in a cosmic game whose madness knows no end—a game of ancient vengeance between the powers who seeded the galaxy with life, and the Forerunners who expect to inherit their sacred Mantle of duty to all living things. In the company of a young girl and an old man, Chakas begins an epic journey across a lost and damaged Halo in search of a way home, an explanation for the warrior spirits rising up within, and for the Librarian's tampering with human destiny. This journey will take them into the Palace of Pain, the domain of a powerful and monstrous intelligence who claims to be the Last Precursor, and who now has control of both this Halo and the fate of Forerunners and Humans alike. Called the Captive by Forerunners, and the Primordial by ancient human warriors, this intelligence has taken charge of, and retasked, the Master Builder's cruel researches into the Flood—which it may have itself unleashed on the galaxy more than ten thousand years before.

In the last years of the Forerunner empire, chaos rules. The Flood—a horrifying shape-changing parasite—has arrived in force, aided by unexpected allies. Internal strife within the ecumene has desperately weakened Forerunner defenses. Only the Ur-Didact and the Librarian—a husband and wife pushed into desperate conflict—hold the keys to salvation. Facing the consequences of a mythic tragedy, one of them must now commit the greatest atrocity of all time—to prevent an unmatched evil from dominating the entire universe. This is the third and final volume of The Forerunner Saga.
