The Penrose appeared without warning. One day the sky was empty, and the next it was filled by an impossibly shaped monolith. Penrose technology was reverse-engineered, accelerating our understanding of physics, materials and computing by centuries. Mankind hurtled forward on an alternate historical trajectory… and desolation ensued. As Mark and Don Leslie, two brothers torn apart by tragedy, explore the post-apocalyptic African wasteland to discover villages, destroyed cities, and uncover the secrets of strange and abandoned technology. But beware, newcomers are either revered or hated.
