I found this on my library shelf back in 2000: Ann Chamberlin’s Leaving Eden.

This is a retelling of the Biblical story of Adam and Eve, and Chamberlin gives us a mythic tale set in a real world. She does a beautiful job of weaving myth, anthropology, religion, story and human nature into a tale that I found believable and compelling. It’s like a geode: a rough, earthy, dun-colored stone with a center that is alive and glowing and mysterious.
