Query: The true biography of a humanitarian

Border Angel was written by newspaper reporter Bill Starr. He knew his subject Frank Ferree, and the situation in which Frank Ferree lived. Frank was a humanitarian amd a humble man. He was a male, non-denominational "Mother Teresa" type who ministered to the needs (mostly the practical food, housing, job and health needs) of thousands of the poor in Cameron County, Texas and adjoining Mexico. He circulated freely with the poorest of the poor as well as presidents and statesmen of his time. This is a truly uplifting story that deserves a good read. It may change your life for the better.
