This is a radio program, so my Kindle readers will have to visit the link above via computer to listen to it. It's pretty interesting.
Here's the subject:
Award-winning investigative journalist Eliza Griswold talks about the tenth parallel—the line of latitude 700 miles north of the equator—the geographical and ideological front line where Christianity and Islam collide. In The Tenth Parallel Griswold looks at Nigeria, the Sudan, Somalia, Indonesia, Malaysia, and the Philippines—places where religious conflicts are also conflicts about land, water, oil, and other natural resources, and where local and tribal issues are often shaped by religious ideas.
