The pupil, Adam and teacher, Sarah's relationship and marriage has real depth, drama and compassion. When Adam reveals his supernatural power it adds intrigue and the dilemmas faced by the couple are skillfully handled. Simon Bailey has an easy style and the story rattles along as Adam's power begins to exert more influence on the couple's lives . I particularly enjoyed the way Adam's power was realistically handled. Also the couple have more than their fair share of difficulties in their careers. As Adam's power evolves and dominates his life it brings on a gripping climax and a highly original ending..
