What is the author's tone in Kaffir Boy: The True Story of a Black Youth's Coming of Age in Apartheid South Africa by Mark Mathabane?

The tone of Kaffir Boy takes the reader on a roller coaster ride of severe drops, wild curves, and steep climbs relieved by very few level straightaways. At times ironic or didactic, it moves rapidly from fear, to reassurance, to anger, to despondency, to determination, to hope, to disappointment, to despair, to elation. The resulting mood changes provide readers with a real sense of having walked in Mathabane's shoes, forcing them to confront headon the evils of apartheid and other forms of racism.
