The Original Series
From Halopedia, the Halo wiki
The Original Series is the retroactive name given to the original four Halo novels. It consists of Halo: The Fall of Reach (2001, Eric Nylund), Halo: The Flood (2003, William C. Dietz), Halo: First Strike (2003, Eric Nylund), and Halo: Ghosts of Onyx (2006, Eric Nylund).
The series covers the origins of SPARTAN-II program and SPARTAN-III program, with a particular focus on John-117 and Blue Team. As the original novels, these books form the groundwork for the majority of Halo lore released after 2006. These novels also set up the events of the original trilogy of Halo games, Halo: Combat Evolved, Halo 2, and Halo 3.
