In the Service of Shadows

Logan has never wanted to hear the dead. He wants nothing more than to ignore the haunting whispers and the strange things that only he can see. But he can't ignore a woman in danger, and the enigmatic Salome Trasmoz is undeniably haunted by an evil spirit that seeks to do her harm.
No good deed goes unpunished, and in helping Salome escape her spiritual stalker, Logan discovers not everyone shares his reluctance to meddle in the supernatural. Some seek out powers beyond their control, and don't care who has to die along the way.
