Children are diamonds : an African apocalypse : a novel / by Edward Hoagland.

Meet Hickey, an American school teacher in his late thirties who goes to Africa as an aid worker. Working for an agency in Nairobi, one of his jobs is to drive food and medical supplies to Southern Sudan to an aid station run by Ruth, a middle-aged woman, who acts as nurse, doctor, hospice worker, feeder of starving children, and witness. Ruth is gruff but efficient, and Hickey, who is usually drawn to youth and beauty, is struck by her devotion. Returning to Nairobi, he can’t forget what he has seen. When the violence and chaos in the region increase to a fever pitch and aid workers are being slaughtered or evacuated, Hickey is asked to save Ruth overland by Jeep. What happens to them and the children that have joined their journey is the searing climax of this novel. Hoagland paints an unflinching portrait of a living hell at its worst, and yet amid that suffering there is hope in the form of humility, sacrifice, and life-affirming friendship.
