The Piper's Graveyard by Ben Farthing
A mysterious evil haunts a small town’s radio waves.
Cessy returns home to search for her missing sister.
She finds a half-abandoned town under siege by unexplainable threats. Attics and crawlspaces are stretch into endless tunnels. Corpses turn up riddled with holes—holes that slither through flesh like insectile parasites. It all leads deep into the abandoned coal mine.
Cessy’s sister disappeared while investigating the vengeful voice on the radio. To find her, Cessy will have to unravel the dark mystery wriggling up from the coal mine.
