The Woman Code by Sophia A Nelson is mostly Biblically based advice without Biblical references. Much of what I read in this book lines up with the same advice you'll find in scripture. I do wish she'd cited the Bible as the foundation for good advice and for the guidebook to living life. I was underwhelmed with this book. While the "codes" are good, they just didn't sound like something I'd never heard before.
This would be a good book for women who are searching for answers and for women who aren't secure in themselves and their relationships.
