In a city that has lost its shimmer, Lindanathi and his two friends Ruan and Cecelia sell illegal pharmaceuticals while chasing their next high.

Lindanathi, deeply troubled by his hand in his brother’s death, has turned his back on his family, until a message from home reminds him of a promise he made years before.

When a puzzling masked man enters their lives, Lindanathi is faced with a decision: continue his life in Cape Town, or return to his family and to all he has left behind.

Rendered in lyrical, bright prose and set in a not-so-new South Africa, The Reactive is a poignant, life-affirming story about secrets, memory, chemical abuse and family, and the redemption that comes from facing what haunts us most.

From the award-winning writer of The Reactive, Triangulum is an ambitious, often philosophical and genre-bending novel that covers a period of over 40 years in South Africa's recent past and near future -- starting from the collapse of the apartheid homeland system in the early 1990s, to the economic corrosion of the 2010s, and on to the looming, large-scale ecological disasters of the 2040s. In 2040, the South African National Space Agency receives a mysterious package containing a memoir and a set of digital recordings from an unnamed woman who claims the world will end in ten years. Assigned to the case, Dr. Naomi Buthelezi, a retired professor and science-fiction writer, is hired to investigate the veracity of the materials, and whether or not the woman's claim to have heard from a "force more powerful than humankind" is genuine. Thus begins Triangulum, a found manuscript composed of the mysterious woman's memoir and her recordings. Haunted by visions of a mysterious machine, the narrator is a seemingly adrift 17-year-old girl, whose father never recovered from the shock of losing his wife. She struggles to navigate school, sexual experimentation, and friendship across racial barriers in post-Apartheid South Africa. With extraordinary aplomb and breathtaking prose, Ntshanga has crafted an inventive and marvelous novel.
