The Dead Room by Heather Graham

Heroine Leslie MacIntyre is an archaeologist with the ability to see and talk to ghosts. A year ago she was at an event when a gas line exploded killing her fiance, Mark Connolly and three others, and injuring Leslie while also enhancing her supernatural ability. Over the past two to three months, several prostitutes have gone missing as well as social worker Genevieve O'Brien, related to socially prominent Eileen Brideswell, who was trying to help the prostitutes get off the street and into a safe, secure life. Private Investigator Joe Connolly has been hired to find Genevieve. If you like ghost stories this is probably pretty good, but I couldn't get caught up in the story line. Sandy P
