The rising population known as "nones" for its members' lack of religious affiliation is changing American society, politics, and culture. Corinna Nicolaou is a none, and in this layered narrative, she tours America's major traditional religions to see what, if anything, one might lack without God. Though she remains a devout none, Nicolaou's experiences reveal points of contact between the religious and the unaffiliated, suggesting nones may be radically revising the practice of faith in contemporary times.
