"Halo: The Flood" by William C. Dietz is a novelization of the first Halo video game. When the UNSC ship Pillar of Autumn crash-lands on the mysterious ringworld Halo, Master Chief Petty Officer John-117 must battle overwhelming Covenant forces while protecting humanity's darkest secrets. A far deadlier threat soon emerges: the Flood, an ancient parasitic species capable of consuming all sentient life. As the parasite devours human and Covenant forces alike, the Master Chief, aided by his AI companion Cortana and a squad of surviving Marines, races to prevent Halo's activation before it unleashes galactic devastation upon all living things.
