Enoch - And after that Enoch both †gave† and began to recount from the books. And Enoch said:
'Concerning the children of righteousness and concerning the elect of the world, And concerning the plant of uprightness, I will speak these things, Yea, I Enoch will declare (them) unto you, my sons:
According to that which appeared to me in the heavenly vision, And which I have known through the word of the holy angels, And have learnt from the heavenly tablets.'

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
