An original full-length Halo novel tying directly into the latest entry of the New York Times bestselling video game series, Halo Infinite. December 2559. Humanity has its back against the wall after the United Nations Space Command flagship Infinity drops out of slipspace into a devastating ambush launched by the Banished. As this fierce enemy alliance seeks to claim a mysterious object hidden within the ancient Forerunner construct known as Zeta Halo, the surviving UNSC corps finds itself compromised and its leadership out of reach-with remaining personnel forced to abandon ship and take their chances on the fractured, unpredictable surface of the Halo ring. Now survival in this strange, alien environment-whether for Spartan super-soldiers or those who never thought they would see the battle up close-is measured day to day against a relentless and brutal adversary that always has the upper hand. Desperation grows, but the will to keep on fighting and enduring no matter the odds is never in doubt . . . even as the Banished seek to unleash a frightening new enemy that could doom them all. . . .
