Mr. Edwards does an excellent job of highlighting and contrasting the past and the present, and wrings a great deal of tension the couple's situation. The sense of fear and evil that he achieves left me wondering until nearly the end of the novel if the incident and it’s source are supernatural in origin. If you want to know you are going to have to read because I am not spoiling it for you.
John and Laura are well-rounded, believable characters. Edwards does a good job of showing them unravel before our eyes. Some of the other characters are solid if unspectacular, with the exception of Alina, whom seems to vibrate with life on the page. There are plenty of twists and turns in the plot, and it never seems to contrived or forced. The prose is smooth and capable, and Mr. Edwards does an exceptional job in showing the characters question and struggle with their grip of reality.
Where Mr. Edwards really shines is in his portrayal of evil. A lot of writers try but he really brings the dark side to life with an almost tangible effect. Without being too disgusting or bloody Mr. Edwards made the hair on the back of my neck stand up more than once. The title of this book is very appropriate, because this novel followed me even after I finished it up.
