Darkness on the Edge of Town is book one in Carson's Laura Cardinal Series. If the rest of the series is as good as the first book I'm going to be reading more of Carson's work.
Laura Cardinal is an investigator with the Arizona Department of Public Safety. It's her job to assist local law enforcement when they need more resources then their department can provide. The abduction and murder of a young girl in the small town of Bisbee starts Laura down the trail of a serial killer. This trail will lead to some answers about a murder that has haunted Laura since she was young girl. This book proves there are some very good novels out there for only 99 cents. Very highly recommended.
