The bestselling adaptation of the iconic video game Halo: Combat Evolved featuring the Master Chief—part of the expanded universe based on the award-winning video game series! 2552. Having barely escaped the final battle for Reach against the vast alien alliance known as the Covenant, the crew of the Pillar of Autumn, including Spartan John-117—the Master Chief—and his AI companion Cortana, is forced to make a desperate escape into slipspace. But their destination brings them to an ancient mystery and an even greater struggle. In this far-flung corner of the universe floats a magnificently massive, artificial ringworld. The crew’s only hope of survival is to crash-land on its surface and take the battle opposing the Covenant to the ground.

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…
