Alongside?

It is not a stream of consciousness or anything like that. We have the narrator, 3rd pesron, who knows everything and who switches from one character to another.He is like omnipresent.
He can tell us how she feels, etc.
I obviously used the wrong term.Sorry, although I didn't say INTERIOR reflection, I meant just going back and retelling her history.
The name of the book is not a secret: Karin Slaughter, 'Blindsighted'
Thank you all, esp Khoff
