Inheriting a family heirloom in the form of an antique clock with a broken moon dial as well as a seaside house in Wales, Grace Morgan mourns the loss of her mother and dreads the manifestation of a family curse that threatens to lay claim to her and everything she holds dear.

Set around the turn of the 20th century, A Moonlit Path of Madness traces Grace's journey from the United States to the distant parish of Newport on the West Wales coast. Partly epistolary and laced with Welsh folklore, this tragic gothic tale delves into the prevalent mental health challenges of the era in the face of unrelenting fear and all-consuming trauma, as Grace reckons with the insidious specter of her lingering grief.
