In Zimbabwe a young American woman is shot dead by a sniper at her camp on the bank of the Zambezi River. In Hong Kong, Lucy Kwok, a Chinese air hostess, returns from Tokyo to find her father, mother and brother have been brutally murdered. The killings are linked — to Africa.

Ex-mercenary Creasy is hired to find the American woman's killers, and when Lucy Kwok discovers that the truth behind her family's death also lies in Zimbabwe, a fateful meeting is set in motion.

Ranging from the African bush to the backstreets of Hong Kong, Black Horn is a towering story of violence, vengeance and a love born of danger.
