"A story of two passionate people who share a shameful past and a tenuous present, this remarkable narrative follows headmistress Mohumagadi -- of the elite Sekolo sa Ditlhora school for talented black children -- and Father Bill, a disgraced preacher, as they are brought together again decades after a childhood love affair expelled them from their communities. Much to the dismay of her students, Mohumagadi hires Father Bill as a teacher, resulting in a battle of wills and wits for the hearts and minds of the children living in the shadow of revolution and change" -- Amazon.com.
