viewpoint - Omniscient but limited Narrator talking to the characters - Pros and cons

It is a third person narrator that changes the character he is "following" from chapter to chapter, or even in the same chapter (just like a limited POV, such as Mistborn or Game of Thrones)

Here are the circumstances:

• It is a post-apocaliptic book with multiple characters in the same survival clan


• The narrator "talks" to these characters. So he is "like" a character too.


• The narrator cannot know what is inside the character's mind unless the character decides to share his thoughts with him (but that character can lie). That's why the narrator is "limited." Depending on how much the character shares his thougts with him, the narrator may use the indirect speech technique.


• The narrator is trustworthy, but the characters may not be.


• He does not give his opinion, so the reader can have his own conclusions without the narrator's voice. (But I also have a doubt about this. Can he have a voice without misleading the reader?)


• I Still dont know who the narrator is (I'm thinking about Death, Spirit or Ghost, but I have my doubts.)

If you want read, here are the reasons I do this:

I do this way in order to make the reader compare the characters and think what is happening inside their heads and their motivations. I will also show informations that many (if not all) characters will not know but the reader does. This will create tension to see how the characters will react to the problem while the reader does not know their interests and motivations. Everything can happen. Because of that mystery behind them, all characters are the chameleon archetype. It's a test of confidence and personality for the reader so he can dive in the story. The reader and the characters will share these same thougts: "can I trust him/her? What she/he is going to do about that? Will the characters work togheter or they will die because of strive for power inside the clan? Will the environment consume the clan or they will survive it?"

What are the pros and cons of these technical features for the narrator? How the relationship of the reader x characters could be affected?
