Sumeria

First time poster.
I just finished a book called "Rule by Secrecy", talks about freemasonry, illuminati and ancient civilizations and many other similar topics. I really enjoyed the book especially the info about ancient Sumeria and the Gods Enki, etc.
Can anyone recommend some good books and or web sites were I can get more info on this?
Thanks,

Zecharia Sitchin wrote alot of books on the subject of ancient Sumeria. Though the validity of his translations are debated.

I have his book "The Wars of Gods and Men : Book III of the Earth Chronicle" I thought it was a very good read. Had some interesting thoeries on the pyramids of Giza aswell
