In Wales, the old powers never died. They're just waiting to be remembered. Dr. Margaret Thornfield arrives at a remote Welsh inn with a simple academic mission: collect folklore, record stories, and return to her comfortable university position. What she discovers will shatter her skeptical worldview and transform her understanding of what lurks at the threshold between our world and the ancient darkness beyond. Over five haunting nights, the innkeeper Cerys Penllyn shares twenty interconnected tales spanning three centuries-stories of the Gwyllgi, the great black hound who guides souls to judgment, and Gwrach y Rhibyn, the shrieking hag who marks those touched by death. These aren't quaint legends for tourist brochures. They're testimonies from those who crossed paths with powers older than Christianity, older than Rome, older than human memory. From Georgian aristocrats who desecrated sacred groves to Victorian ironmasters who built their fortunes on cursed ground, from coal miners who broke ancient compacts to modern professionals who discover some debts span lifetimes-each story reveals the terrible price of forgetting what the stones remember. But as Margaret records these accounts, she begins to notice disturbing patterns. Scratching at her door in the dead of night. Witnesses from the stories appearing at the inn-people who should be decades dead. The Gwyllgi's burning eyes watch from the darkness. And most unsettling of all: the realization that she wasn't randomly chosen for this assignment. She was called. Twenty tales of guilt and redemption. One woman's journey from skeptic to keeper. And the ancient Welsh powers that refuse to be forgotten. Based on authentic Welsh folklore and working-class history, this masterfully structured collection weaves supernatural horror with profound truths about sacrifice, responsibility, and the price of standing between worlds.
