The Shepherd King Duology Review

The moment I picked up One Dark Window, I knew I was in for something special. Rachel Gillig's Shepherd King duology has taken BookTok by storm, and after finishing both books, I completely understand why. If you're searching for a gothic fantasy romance with an original magic system, morally grey characters, and a slow-burn romance that will keep you turning pages late into the night, this completed duology delivers on every front.

What Is The Shepherd King Series About?

Set in the mist-shrouded kingdom of Blunder, this dark fantasy follows Elspeth Spindle, a young woman harbouring a dangerous secret. She's been infected with forbidden magic since childhood, and sharing her mind with an ancient, sardonic spirit she calls the Nightmare. In a kingdom where magic users are hunted and executed, Elspeth has spent her life hiding in plain sight.

Everything changes when she crosses paths with Ravyn Yew, the Captain of the Destriers and nephew to the tyrannical king. Together with a band of misfits, they embark on a treasonous quest to collect twelve magical Providence Cards, the only hope of lifting the curse that's destroying their kingdom from within.

Why Readers Are Obsessed With This Duology

The Shepherd King series stands out in the crowded romantasy genre for several reasons. Gillig has crafted a magic system inspired by tarot cards that feels genuinely fresh. Each Providence Card grants its wielder unique abilities, but magic in Blunder always demands a price. This creates constant tension as characters must weigh the cost of using their powers against the dangers they face.

The gothic atmosphere permeates every page. Fog-drenched forests, crumbling estates, and an ever-present sense of foreboding create the perfect backdrop for this dark fairy tale. Fans of authors like Hannah Whitten, Naomi Novik, and Alexis Henderson will find themselves right at home in Blunder's misty woods.

The Romance: Slow-Burn Perfection

For readers who love an enemies-to-lovers arc with plenty of tension, the romance between Elspeth and Ravyn delivers beautifully. Their relationship develops organically from reluctant allies to something far deeper, with each stolen glance and moment of vulnerability earning the emotional payoff that follows.

The duology also features a secondary romance in Two Twisted Crowns between Prince Elm and Ione that adds another dimension to the story. Both relationships are slow-burn in nature, focusing on emotional connection and trust-building rather than instalove.

In terms of spice level, this series sits at around 1-2 out of 5. There are intimate scenes, but they're not the focus of the narrative. This makes the duology accessible for readers who prefer their romance on the subtler side while still delivering satisfying romantic moments.

Character Depth That Keeps You Invested

One of Gillig's greatest strengths is her characterisation. Elspeth is a compelling protagonist whose internal struggle with the Nightmare creates fascinating dynamics throughout both books. Speaking of the Nightmare, he quickly became one of my favourite characters. This ancient spirit trapped in Elspeth's mind could have been written as purely villainous, but Gillig crafts him with surprising depth, wit, and unexpected tenderness.

The supporting cast shines as well. The found family dynamic among the band of rogues working against the crown adds warmth to an otherwise dark narrative. Prince Elm, in particular, undergoes significant development in the second book, emerging as a fan favourite with his sharp tongue and hidden depths.

What Makes Two Twisted Crowns Worth The Wait

The sequel picks up directly where One Dark Window leaves off with a gripping cliffhanger resolution. Two Twisted Crowns expands the world-building, delving deeper into the history of the Providence Cards and the mysterious Shepherd King who created them.

The addition of multiple POVs in the second book provides fresh perspectives on the story, though some readers may miss the singular focus on Elspeth from the first book. The stakes escalate dramatically, and Gillig ties up the narrative threads in a satisfying conclusion that honours the journey readers have taken with these characters.

Books Similar To One Dark Window

If you're wondering what to read after finishing this duology, consider these recommendations that capture similar elements:

For the Wolf by Hannah Whitten offers comparable gothic atmosphere and forbidden romance. The Serpent and the Wings of Night by Carissa Broadbent delivers enemies-to-lovers tension with high stakes. A Touch of Darkness by Scarlett St. Clair provides dark fantasy romance with mythology-inspired world-building.

Content Warnings

Before diving in, readers should be aware that the series contains violence, gore, blood, self-harm for magic purposes, mentions of violence against children, parental neglect, and grief. Rachel Gillig provides detailed content warnings on her website for those who need more specific information.

My Verdict: 4.5 Stars

The Shepherd King duology earns a strong 4.5 stars from me. Gillig has crafted something special here: a gothic romantasy that balances atmospheric world-building, genuine character development, and swoony romance without sacrificing narrative momentum. The unique Providence Card magic system sets it apart from other entries in the genre, and the Nightmare remains one of the most memorable characters I've encountered in fantasy romance.

Minor criticisms include occasional pacing issues in the second book's middle section and a secondary romance that, while enjoyable, develops somewhat quickly. These are small complaints in an otherwise excellently executed duology.

Should You Read The Shepherd King Series?

If you enjoy dark fantasy, slow-burn romance, morally grey characters, and atmospheric storytelling, this completed duology belongs on your TBR. It's perfect for autumn reading with its misty forests and gothic vibes, though honestly, it's compelling enough to enjoy any time of year.

The fact that it's a completed series is a bonus. No waiting years for sequels here. You can dive into Blunder's fog-shrouded world and emerge on the other side with a satisfying conclusion.

For fans of Fourth Wing, A Court of Thorns and Roses, or Uprooted looking for something with a darker edge and unique magic, One Dark Window and Two Twisted Crowns should be your next read.
