Seventeen-year-old Savannah has always known the story of the curse that strikes the girls in her family: a curse of anger that turns their blood to poison. A rare few will rage and rage until it destroys them.

Savannah doesn't want to believe in magic, but lately things are changing. She can feel the anger simmering and boiling in her blood. In a bid to break the curse, Savannah and her childhood friend Rex plunge into the shadowy underworld of Cape Town, a place of magicians, healers and vuilwitches.

Danger is everywhere - but the greatest danger may be Savannah herself as she fights to harness the lethal power inside her.
