What Genesis Teaches Us About Our Spiritual Identity, Sexuality and Personal Relationships, is a good one. Nicely balanced with good basic information. She, too, participated in PBS's Genesis. A nice little book with portrait meditations is K. Armstrong's In the Beginning . She is the same author of A History of God .
Strong scholars make good books.
These are books that I also have on my shelf, but I have not studied them completely. I continue to refer to them now and there. An Introduction by C. Westermann is a valuable but too technical book. I think that R. Alter's The Art of Biblical Narrative is the fundamental book to have to understand how this approach can enrich our study of the book of Genesis, and the Hebrew Narrative in general. A must have.
