In an unwelcoming English village, two young outsiders are swept up in an archaeological mystery that ends in a startling paranormal twist.
A sense of foreboding sets in the moment fourteen-year-old twins Rachel and Adam arrive from New York to visit their English grandmother. The station is empty, village streets are deserted, locals are hostile, and even their frail Granny Root is oddly distant. And what about the bees that appear to follow a mysterious force? It all seems tied up with the Triskellion — an intertwining symbol etched in chalk on the moors. With a growing sense of danger and white-knuckle suspense, the twins are compelled to unearth a secret that has protected the village for centuries, one that reveals a shocking truth about their ancestors — and themselves.
