In the shadow of Caerphilly's forgotten quarries, where ancient Welsh legends whisper warnings from the deep, Rhodri returns to claim his estranged uncle's crumbling estate. But what begins as a reluctant inheritance unravels into a nightmarish descent into "Weird Wales." A realm where glitches bleed into reality, and the knock-knock of mythical Coblynau miners echoes as a curse.

Haunted by ghostly visions of his lost love and fractured family secrets, Rhodri uncovers a forbidden ledger that weaves time, guilt, and folklore into a trap. As illusions decay and rituals awaken, he must confront the repeating fall of his bloodline. Or become its next victim.

Perfect for fans of Arthur Machen and folk horror, this gripping supernatural novella blends occult mystery, haunted house terror, and Welsh mythology into a concise, atmospheric thrill ride. Will you answer the knock?
