Halo: The Flood

Blurb

Halo: The Flood is a military science fiction novel by William C. Dietz, based on the Halo series of video games and based specifically on the 2001 video game Halo: Combat Evolved, the first game in the series. The book was released in April 2003 and is the second Halo novel. Closely depicting the events of the game, The Flood begins with the escape of a human ship Pillar of Autumn from enemy aliens known as the Covenant. When the Pillar of Autumn unexpectedly discovers a massive artifact known as "Halo", the humans must square off against the Covenant and a second terrifying force in a desperate attempt to uncover Halo's secrets and stay alive. Though the book roughly follows the same events of the Xbox game, featuring identical dialogue, Dietz also describes events not seen by the game's protagonist, the super-soldier Master Chief.
After the success of the first Halo novel, Halo: The Fall of Reach, publisher Del Rey and Halo publisher Microsoft signed a deal for new books based on Xbox games, including another entry in the Halo series. Del Ray approached author Dietz to write the next book.
