The Tenth Parallel, by Eliza Griswold

Eliza Griswold's book is a nearly perfect puzzle. On the one hand, she is doing some of the most important religious journalism being done these days. If God has, as one of her interview subjects puts it, "moved his work to Africa," then Griswold possesses a sharp pair of eyes for God's new work. It doesn't hurt that Griswold writes like an angel and has an eye for irony and detail.
