X-link to the DRM-free thread for a new StoryBundle:
The Fear Bundle curated by Kristine Kathryn Rusch contains mainly newer titles by established authors and some indies, focusing on a multi-genre theme, with suspense-oriented selections ranging from serial killer thrillers to outright supernatural horror.
Plus, if you enjoy RPG tabletop gaming, Bundle of Holding has a bunch of spooky Halloween offerings for horror-ish game settings, including some British Lovecraftiana.
