Tyndale House's In the Presence of My Enemies, which recounts the year-long captivity of missionaries Martin and Gracia Burnham at the hands of Abu Sayyaf Group, a militant Muslim group in the Philippines, is now a play, according to Kansas television station KAKE's web site. The Burnhams served with New Tribes Mission in the Philippines for 17 years. The book, written by Gracia Burnham with Dean Merrill, received a Gold Medallion award from the Evangelical Christian Publishers Association in 2004.
