Both insightful and intrepid, Eliza Griswold journeyed through Africa and Asia along the tenth parallel, the line of latitude 700 miles north of the equator where nearly 25% of the world’s Muslims and Christians compete for resources, converts and political power. A poet with an ear for simple but evocative language, Griswold takes the reader through the dust of encroaching desertification as she attends an indigenous Indonesian wedding, meets with African rape victims, sits with a Muslim religious leader as he tries to resolve local disputes, and observes an election where voters line up in a barren field behind the candidate of their choice. After reading about her meetings with the homosexual and Muslim denouncing Anglican Bishop Akinola of Nigeria I still have no sympathy with his views, but I now have some understanding of why he thinks the way he does. Griswold’s own empathy serves her well; believers on both sides of the religious divide open up to her. As an agnostic daughter of the former presiding bishop of the Episcopal Church, Griswold even shares a flash of private connection with crusading evangelist Franklin Graham when she meets him in Africa—though they have very different ideas they are both PKs, preacher’s kids, with childhoods that were a struggle between belief and rebellion. My copy of THE TENTH PARALLEL is tabbed with more than 30 post-it notes marking sections I thought were so perceptive and illuminating I knew I’d want to read them again.
