Actually if you really want to know more about Lucifer, the fallen angels and other stuffs, you have to read the books which were removed from the original Hebrew Bible. Our Bible today has already been changed. As far as I know there are 75 or more books that were removed. We have so much questions about our Bible today that is hard to understand and interpret. When you read those missing books which were removed, it would be of great help to understand more. I suggest you read first "CAVE OF TREASURES BOOK 1 'BEFORE GENESIS''' then go for the rest of the other books. Maybe "The Book of Enoch" which is much popular I guess.
