Gary Smith worked as a priest for Sudanese refugees in northern Uganda for six years. He wrote a book about his stay, They Come Back Singing, in which he pays tribute to the simple faith and admirable strength of the people who live in the precarious conditions of refugee villages in northern Uganda. Among other things, the book draws attention to the humanitarian disaster and long-term human suffering, which remains somewhat outside the media's attention. In both Sudan and Uganda, several different factions are at war with each other; the greatest fear is the God's Resistance Army led by Joseph Kony, which commits atrocities on children from the attacked villages: boys are forced to fight and kill by drastic methods, girls are abused as sex slaves.
