I and the other family's dad are doing Omnibus, and our wives are planning to cover the rest.
Good luck with that! Seriously. I was really impressed with the Omnibus book,and ordered it, but found it was beyond me to teach by myself. I have left the books on the book shelves for the kids to pick up whenever and they have read a couple of them on their own. You may want to read the Gilgamesh Epic with yours as there are graphic sexual themes. We ended up opting not to have ours read it.
