In 'The Dead House,' artist Maggie Turner seeks solace from her tumultuous past in an isolated cottage on Ireland's rugged coast, only to find herself ensnared in a chilling web of supernatural occurrences. Disturbed by unsettling visions and voices, Maggie's reality blurs with haunting echoes of ancient Celtic folklore. The novel crescendos with a spine-tingling unraveling of Maggie's artistic obsession intertwined with the malevolent spirit known as 'The Master,' awakened from the depths of time through an ill-fated Ouija board session. O'Callaghan's prose weaves a compelling narrative, showing how Maggie's quest for peace is thwarted by the insidious grip of a curse long-rooted in the craggy landscape.
