Amiga Khalo is a two-million-dollar investment. As the adopted daughter of Sandton's most elite family, her life is a curated masterpiece of silk jumpsuits and high-stakes social climbing. But when a single cruel comment shatters her sense of belonging, Amiga trades the skyscrapers of Johannesburg for the red dust of Ga-Masingita. She returns to find the mother who gave her up twenty years ago, but she doesn't find a tearful reunion. She finds Masingita—a traditional healer with a sharp tongue and an even sharper understanding of the "Physics of the Soil." Fueled by "Sandton Evil" and a desire for vengeance, Amiga begins to study the ancient botanical secrets of the Limpopo bush—not to heal, but to craft a final, lethal grudge. But when a family emergency strikes, Amiga must decide if she will use the poison she's brewed to kill the past, or the medicine she's found to save her future. The Hybrid Heart is a razor-sharp contemporary thriller about the debt we owe our ancestors and the chemistry of who we really are.
