Any good books to learn about this theory?

They're a group created by the higher ups to disinform and misinform the public. They are not the ones you should be reading up on.

no, they are the ones you should be reading on,
but you have to watch what and where you read,
because as you said they are known to misinform

I recommend reading
"The Protocols of the Elders of Zion"

about 70 page , it's about NWO / illuminti how they plan and think.
really interesting stuff
