DCI Allison St Clair has cheated death- but only just. She is weakened and desperately needs rest. But something calls to her from ancient Cornwall where a sickening wave of bizarre murders has local police well out of their depth. The problem is, they just don't know it. She has been sent on compulsory leave to recuperate from her recent ordeals, but she cannot rest. She must somehow halt the killing spree. But how? A London-based Detective Chief Inspector no matter how talented, has no jurisdiction in Cornwall. Revelations from Cornwall's deep past are uncovered during the Midsummer Golowan Festival- a gathering whose primeval rituals and bonfires have been badly misunderstood. Human frailty has opened the door for the insidious Mister Black and a new, elemental force to choke-off our one hope for the future. Only Allie St Clair and the magnificent Michael could stand in their way, but time is the enemy. In a furious twenty-four hours, all will be saved or irrevocably lost. The Game has taken a new, deadly twist and this time, on a mountain floating on a black sea, the future of humanity will be decided.
