After aspiring novelist Jake Conley regains consciousness from a coma, he discovers he’s affected by synaesthesia, and that his now cross-wired brain endows him with heightened psychic powers.
Jake’s research on the Northumbrian King Aldfrith takes him to Elfrid’s Hole in North Yorkshire, where – as legend relates – the king sheltered after a bloody battle. What Jake doesn’t realize is that his investigation has unleashed a series of deadly paranormal events, in which Jake himself becomes the prime suspect.
Fighting to clear his name and overcome the hostility of Detective Inspector Mark Shaw, can Jake follow through – and bring peace to a soul tormented by over a thousand years?
