The book is entitled The Locust Effect: Why the End of Poverty Requires the End of Violence, and it's penned by Gary Haugen (International Justice Mission) and Victor Boutros (U.S. Department of Justice). With endorsements from QIdeas and others, and a good review by TGC, you might want to check this book out.
Gary Haugen, IJM's founder and president, has spoken at my undergrad's chapel. The Gospel is the reason he does what he does. Below is the trailer.
