Nothing to Fear

I've read Nothing to Fear by Karen Rose about a vengeful woman, Sue Conway, who has a list of people she feels caused her to be sent to prison for about five years.  She systemically goes about her murders of several people and kidnaps the 11-year-old son of a woman whom she says betrayed her.  She demands Five million dollars.  A private detective, Ethan is asked by the boy's parents to find him.  Ethan meets a young woman, Dana, who runs a shelter for battered woman.  Sue goes to the shelter with the boy who is deaf and claims she is running away from a brutal husband.  There is a romance between Ethan and Dana which permeates throughout the book.  There are a number of murders and assaults and twists and turns.  Glad to finish it. 31/2/5
