Ring Shout is a novella from P. Djèlí Clark that puts a seriously creepy supernatural spin on the Ku Klux Klan of the 1920's. Opportunistic monsters that feed on human hatred have found their perfect food source in the Klan, and as ordinary human Klansmen unleash metaphorical hell on Black Americans, the monsters plot to unleash very literal hell on everyone. Luckily, Maryse Boudreaux and a few other freedom fighters can see them for what they truly are. Armed with swords, rifles, and Gullah folk magic, they're fighting to save the world from its own devastating hatred. Ring Shout clocks in at less than 200 pages, so it doesn't take long to read, but it'll stay with you for a long time afterward.
