Katherine Ozment is the author of "Grace Without God: The Search for Meaning, Purpose, and Belonging in a Secular Age." She has worked for National Geographic and Boston magazine and been published in the New York Times. She lives in Chicago with her husband and three children.

For years now, she has been exploring how the ever-growing segment of non-religious parents raise their children. They're not all atheists, but they have to grapple with the Big Questions about life and death and belonging, all without supernatural faith. She wrote a magazine article about it a few years ago, and she has now written a full-length examination into the topic.

I spoke with her about what secular "grace" looks like, why atheists may want rituals traditionally reserved for the religious, and how the landscape for atheist parents is rapidly changing.
