Whispers from the Swamp - C. A. Varian - Bog

The swamps near New Orleans harbor more than snakes and gators... There are monsters of legend... and the spirits left behind whisper in your ear.
Many changes are happening in the life of Hazel Watson... good changes... but the demands of the spirit world remain the same. The exhausting, stressful obligations she's dealt with since she was a child. Helping them is inescapable.
So, when the bodies of two women are discovered in the swamps of South Louisiana, the people of New Orleans are shocked... but not Hazel. She had been seeing the faces of those same two women in her dreams for weeks, haunting her and beckoning her to find their killer.
Having never been comfortable with sharing the nature of her abilities with others, Hazel struggles with having to do just that when she receives a ghostly warning about the impending abduction of another woman.
Can Hazel overcome her fear of being exposed, and of the swamp itself, before more women fall victim to the killer who stalks the Louisiana wetlands?
