Hlomu the Wife, by Dudu Busani-Dube

Essentially a love story that takes its cues from life in a South African township 

A young woman named Mahlomu meets Mqhele Zulu and they fall in love. Even though aspects of Mqhele's personality and past make her uncomfortable, Hlomu is happy. Their love is strong and they stand by each other through good and bad. But Mqhele and his seven brothers have a dark and tumultuous past that involves a dead warlord father, mob justice, and lots of unaccounted-for money.

The Zulu brothers are rich, handsome, powerful and dangerous. They eventually become one of the wealthiest and most powerful families in Johannesburg - but the inherent danger remains.
