At the moment, the most pivotal books are the Nylund Trilogy and the Forerunner Saga. [b][u]Nylund Triligy[/u][/b] The Fall of Reach First Strike Ghosts of Onyx [b][u]Forerunner Saga[/u][/b] Cryptum Primordium Silentium If you have the money, I'd also recommend Kilo-5 Trilogy as well as that sets the stage for Halo 4 and beyond. [b][u]Kilo-5 Trilogy[/u][/b] Glasslands Thursday War Mortal Dictata As for comics, you'll want to get Halo: Escalation. It looks like we're slated to get a total of 24 issues, so not all of them are here yet. Each issue generally goes for about $4 individually, but you can buy them in Volumes for a much cheaper price. We've got two Volumes out right now I think. So look to get the four Volumes of Escalation.
