Anna May Jones is the daughter of a coal miner. When her father succumbs to Black Lung, the coal company wastes no time in turning the family out of their home. In desperation, Anna May's mother sends her to live with her Aunt Jinny, a witchy-woman and an Elemental Master, in a holler outside of Ducktown. As she settles into her new life, Anna May finds herself falling for a stonemason with such a talent for stonecarving that people come all the way from Memphis to commission statues and tombstones from him. But he's not content with his current skill—he wants to learn to carve stone so well it looks real. When the stonemason disappears on a quest to fulfill his ambition, it is up to Anna May to follow and find him, armed with the new abilities Aunt Jinny has taught her. To save the man she loves, Anna May must journey into the mountain—and confront the horrors that lurk in the darkness of the mine.
