Plenty of horror stories have something monstrous at their center. For some, the monster comes from somewhere else: another world, an isolated space, somewhere mysterious. With others, the monstrous emerges from within: think about nearly every vampire or werewolf story, and how the familiar is slowly corrupted into the terrifying. There are certainly works that bridge the gap between the two: Sarah Langan’s The Keeper, in which a troubled young woman becomes the haunted vessel for a town’s unease and corruption, is a prime example. The four works collected in Mame Bougouma Diene’s Dark Moons Rising on a Starless Night venture into a similar space. Here, the creatures that bedevil communities are not far removed from the needs of the community themselves, leading to an unsettling duality.
