About the book

One Dark Window by Rachel Gillig is a richly atmospheric dark fantasy romance and the first book in The Shepherd King duology. Blending gothic aesthetics with folklore-inspired magic, the novel delivers a haunting story of curses, prophecy, and survival in a world ruled by fear of the unnatural.

Set in the mist-covered kingdom of Blunder, the story follows Elspeth Spindle, a young woman burdened with a dangerous secret. In a land where magic is outlawed and those who possess it are hunted, Elspeth harbours an ancient presence within her mind—one that grants her power at a terrible cost. This internal struggle creates a constant sense of tension, as every use of magic risks exposing her to execution or losing herself entirely.

Magic in One Dark Window is governed by a system of Providence Cards, relics that bestow specific abilities while exacting steep personal prices. These cards form the backbone of the novel’s world-building, reinforcing the idea that power is never free and that desperation often fuels dangerous choices. As Elspeth becomes entangled in a plot to gather the complete deck and save the kingdom from a spreading curse, the stakes escalate rapidly.

At its core, the novel is also a slow-burn romance built on mistrust, secrecy, and reluctant cooperation. The relationship develops gradually as alliances shift and truths emerge, allowing emotional connection to grow organically amid danger. Rather than overshadowing the plot, the romance is tightly woven into the story’s themes of control, autonomy, and sacrifice.

Gothic atmosphere permeates every page, from shadowed forests and crumbling keeps to whispered legends and religious paranoia. Gillig’s prose emphasises mood and tension, creating an unsettling sense that the past is never truly gone and that fate is always watching. The presence of prophecy and visions further blurs the line between choice and destiny, adding psychological depth to Elspeth’s journey.

One Dark Window is ideal for readers who enjoy dark romantasy, morally grey characters, and intricate magic systems rooted in folklore. Fans of eerie settings, cursed protagonists, and emotionally charged storytelling will find this novel a gripping and immersive introduction to The Shepherd King series.
