The Karoo Signal

by Thomas Mokoena

Night-shift technician Nomsa Dube likes the Karoo because it is honest at night: no wind, no traffic, just ten thousand stars and the hum of the radio dishes. Then, at 02:14, the hum changes pitch — and a pattern begins to repeat every twenty-seven minutes. A tense, big-hearted first-contact story set under the darkest skies on Earth.
