The October Killings - Yudel Gordon Stories, #4

Abigail Bukula was fifteen years old when her parents were killed in a massacre of anti-apartheid activists by white apartheid security forces. Because a young soldier spoke up in her defense, she was spared. Now she's a lawyer with a promising career in the new government, and while she has done her best to put the tragedy behind her, she's never forgotten Leon Lourens, the soldier who saved her life. So when he walks into her office almost twenty years later, needing her help, she vows to do whatever she can.  Someone is slowly killing off members of the team who raided the house where her parents were murdered, and now Leon and an imprisoned colonel are the only targets left. Abigail turns to Yudel Gordon, an eccentric, nearly retired white prison psychologist for help.
To save Leon's life they must untangle the web of politics, identity, and history before the anniversary of the raid-only days away.
