Summary
Four-and-a-half years after the end of the Human Covenant War, Spartan John-117 and the UNSC Artificial Intelligence Cortana continue their story. Marooned on the mysterious world of Requiem, John must contend with the potential loss of his trusted friend and companion, as she begins to suffer the early onset of A.I. Degeneration-Rampancy.
But getting her help will not be easy. The Covenant have reformed under a new leader, and have come to this unknown world, seeking, and allying with, an ancient evil buried within, whose grudge against humanity is older than the Halos themselves.
But Chief won’t be alone. His Spartans in arms, Blue Team, led now by Spartan Jun-A266 of Noble Team, have arrived alongside the UNSC Infinity. In the wake of the Infinity’s crash landing on the planet, and beset on all sides by secrets, enemies, and shattered dreams, can the legendary Spartans stand against the mysterious Forerunner known only as the Didact? And will they be able to save Cortana, in the end?
