The Place of Hungry Shadows [EPUB ebook] 

Deep beneath the earth, something ancient and malevolent stirs. When Lee-Anne and her husband Geoffrey become trapped in an abandoned mine, they uncover horrors beyond imagination-an entity that feeds on lost souls and bends reality to its will. As Lee-Anne fights to save Geoffrey from possession, she unknowingly awakens forces that refuse to stay buried. Years later, just as they begin to rebuild their lives, a chilling phone call shatters their fragile peace. The mine never forgets. And it’s not done with them yet.
