An award-winning investigative journalist and poet, Eliza Griswold has spent the past seven years traveling between the equator and the 10th parallel (the line of latitude 700 miles north of the equator) at the geographic and ideological front where Christianity and Islam collide. In The Tenth Parallel, Griswold illustrates how faith is shaped by geography and demographics and how one's sense of God is shaped by one's place on earth.
