Two sisters grow up in the same home, their mother dead from an overdose, their father just gone; raised by their cold-hearted grandmother in a cold house. But they grow up to be two very different people. Kacey, the vibrant, popular one, succumbs to the siren call of the street and becomes an addict and a prostitute. Mickey, the quiet one, joins the police force and patrols the squalid streets of the Philadelphia neighborhood where her sister lives and works. Though they don't talk anymore, Mickey sees her sister from time to time, until suddenly she doesn't. Kacey has disappeared at the same time as other girls from the neighborhood are turning up dead. Has Kacey met the same fate? Mickey puts her job and what little family she has left at risk to find out what happened to her sister. Good book. The characters and their relationships are complex and well thought out. The mystery moves along at the perfect pace. The writing style is one you don't see every day and that's fitting, because you don't read a book like this every day.
