Hotwire: Requiem for the Dead, Vol. 1

Detective Alice Hotwire lives in a place where the dead share the same space with living. Most of the dead, better known as "blue lights," are the same harmless, witless drones lost in their death as they were in life. Some of these electrical manifestations of their former selves want revenge. Some want power. Some even want company to join them in the ranks of the departed. Enter Alice Hotwire, Detective Exorcist. She is the best person at keeping the peace on the blue light beat.  It's a job she doesn't want in a world she doesn't understand. But when a break-in at the Maximum Security Necropolis sets off a surge of violent hauntings, Alice knows she's the only one that can keep the blue lights in line and pull the city from the brink of chaos.
