Blood to Poison (Broché)

It's a sinister family heirloom ; passed down through the bloodline for hundreds of years, with one woman in every generation destined to die young. The family calls them Hella's girls - named for their ancestor Hella, the enslaved woman with whom it all began. Hella's girls are always angry, especially in the months before they die. The anger is bursting from Savannah - at the men who catcall her in the street, at her mother's disingenuous fiancé, even at her own loving family.
Each fit of rage is bringing her closer to the edge, and now Savannah has to act to save herself. Or die trying. Because the key to survival lies in the underbelly of Cape Town, where the sinister veilwitches are waiting for just such a girl.
