Quick question about Halo 5 and the books

Hi,

Just a quick question.

For the moment i read only 4 of the Halo books.
If i’m right Halo 4/5/6 is the story of the forerunner trilogy, so, is the story with Cortana, and all what happened in halo 5 inside of one of those 3 books?

I want to understand the story better ^^

up :3

Not really, but if fan theory’s are correct all we need to understand Cortana’s sudden change of heart are Halo 2/Halo3 (Grave mind torturing her, Logic plague) and Halo 4 (Rampant parts of Cortana surviving). The logic plague is shown in the Forerunner books but the Halo 3 terminals might also mention it as well.
