Trivia
- In most of the novels, there is a Covenant subplot. These usually feature Grunts such as Yayap or Dadab.
- There is the Marathon symbol between the "A" and "L" of Halo on the cover of each novel.
- The novels have many errors, including typos, as well as several contradictions to the games. This is likely because that there were different authors which are also not part of Bungie Studios.
