‘False Bible?’

As a kid, I remember going to the adult section of the library and getting a ‘Bible’ and I think the name started with a Q or K but anyways I think the first book was genesis and talked about hell. I believe it was trying to say that satan was actually god or something. After looking it up the Wikipedia stated it was know as a ‘false Bible’.

This was many years ago and was curious if anyone knew about this. I can’t remember the name of it anymore.
