Look, that had nothing to do with the thread.
One thing was that they were surprised that half of "Reach" was destroyed. In the book, everything in Reach knew the Covenant were attacking.
Another was that there were Slipspace ruptures behind the Defense Grids. In the book, this would be impossible (untill later on) for the Covenant because of gravity messing up the slipspace calculations.
I think there might be reasonable explanations for all this, but they are good example of how this could be a sequel set years after Halo 3.
