Query: Waking Up

"A Dry White Season" is a classic South African novel. The story is set in the 1970s, during the police crackdown after the Soweto riots. The "hero" is a mild-mannered Afrikaner schoolteacher who wakes up to the real conditions in South Africa when his school's black gardener dies in police custody. The teacher sets out to investigate the death, only to draw the attention of the police and the ire of his family and colleagues, who don't understand why he wants to "cause trouble." The book brilliantly links the personal and the political, but it isn't merely a "political" novel. Rather, it's a close examination of what it means to see the world through the lens of an aroused conscience. As such, "A Dry White Season" is a rarity -- a page-turner that grips the reader while also making him think hard about personal accountability in the face of injustice and corrupt institutions. Fans of Graham Greene will love it.
