Out of Shadows by Jason Wallace

Set in Zimbabwe in the 1980s, just after the war for independence, a young English boy, Jacklin, is torn between his black friends at school and his sympathy for the colonial whites after witnessing the compulsory land seizures by Robert Mugabe's government.

But with an imminent visit by Robert Mugabe to the school, Jacklin realizes that Ivan, his white supremacist schoolmate, plans to assassinate the black leader. The novel leaves us with the moral dilemma — in hindsight, should Jacklin have killed Ivan or let Ivan kill Robert Mugabe?
