I have read both the book of Book of Jubilees and Enoch. I actually found Enoch to be very interesting. I don't really remember anything about Jubiliees because I got bored half way through it. I never really got back to it or finished it. If I remember correctly it just seemed like another version of Genesis to me. You can probably find most of them online. I have a .pdf of the book of Enoch and I know you can find it in the bookstore also. Enoch was actually really interesting. It describe how these angels called watchers took humans for their wives. They taught people to the secrets of heaven, how to make weapons of war, and how to make cosmetics. They reproduced with the humans and created half human, half angel things. They are also the reason for the flood. They were considered an abomination in the eyes of the Lord. Thats just the short version though of the part I found most interesting.
I did a search and found the Book of Enoch online. here is the link..
