Belfast, 1847. They would come to call it Black '47. A town on the brink, ravaged by the Great Hunger sweeping across the island of Ireland. A town living in fear as a crazed killer stalks the streets at night, butchering young women. They call him Bloody Hands. Amidst the chaos, nineteen-year-old Maggie Malone and her young brother, Jinks, fight to survive each day. But there is worse to come when a mysterious ship limps into port, having miraculously emerged from a savage storm. A ship carrying death itself, summoned by a malevolent force that has haunted the mountain overlooking Belfast for centuries, hellbent on devastation and ruin. They call her The Black Lady.

Maggie and Jinks become unwitting pawns as Bloody Hands and The Black Lady take their ancient feud to new levels of barbarism, threatening the future of Belfast and its hapless population. Can Maggie unlock the dormant power within her and save Belfast from toppling into the abyss? Can she transform into the savior that the people so desperately need? Can she become The Famine Witch?
