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. Facing the imminent collapse of their civilization, the Forerunners known as the Ur-Didact and the Librarian reveal what they know about the relationship between the long-vanished race of the Precursors and the Flood. While the Precursors created many technological species, including those of the Forerunners and humanity itself, the roots of the Flood may be found in an act of enormous barbarity, carried out beyond our galaxy ten million years before. Because of that savagery, a greater evil looms. Only the Ur-Didact and the Librarian—husband and wife pushed into desperate conflict—hold the keys to a solution. As they face the consequences of a mythic tragedy, one of them must now commit the greatest atrocity of all time—a shocking act designed to prevent an insane abomination from dominating the entire galaxy…

One hundred thousand years ago. In the wake of the apparent self-destruction of the alien Forerunner empire, two humans—Chakas and Riser—are like flotsam washed up on very strange shores indeed. Captured by the Forerunner known as the Master Builder and then misplaced during a furious battle in space, Chakas and Riser now find themselves on an inverted world, where horizons rise into the sky and humans of all kinds are trapped in a perilous cycle of horror and neglect. 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 Responsibility 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 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. Their travels will take them into the domain of a powerful and monstrous intelligence—known as “the Captive” by Forerunners, and “the Primordial” by ancient human warriors, this being may not only control the fate of Chakas, Riser, and the rest of humanity, but of all sentient life across the galaxy…

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…
