They Will Burn by Montana Fyre is a spellbinding journey through a meticulously crafted dystopian reality that grips the reader from the get-go, ensuring that the pages keep turning until the final, explosive conclusion. This debut novel not only showcases Fyre’s prowess in creating a hauntingly plausible future but also her ability to sculpt deeply human, flawed, and relatable characters.

Set in a bleak future where the authoritarian regime "The Directorate" enforces absolute control over all aspects of life, They Will Burn introduces us to protagonist Elara, a fiery young rebel determined to break free from the oppressive shackles of societal norms. Elara’s world is richly described, set in a desolate urban sprawl where the sky is perennially gray, punctuated by the stark, imposing architecture of government buildings. The author’s use of descriptive language is both evocative and oppressive, perfectly capturing the claustrophobic atmosphere of Elara's environment.

Elara’s journey is compelling not only because of the physical hardships she endures but also due to her inner turmoil. Montana Fyre masterfully layers Elara’s character, embedding conflicts that resonate well beyond the confines of the book’s pages. Elara’s struggle with her identity, her purpose, and her profound skepticism of the rebel cause adds a richness to her character that is often missing in dystopian protagonists. The supporting cast, too, is well-drawn. From Cale, her stoic and mysterious mentor, to Mira, a fellow rebel who challenges Elara's perceptions, each character enhances the vibrancy and believability of this dark world.

One of the standout features of They Will Burn is Fyre’s exploration of themes that mirror current societal issues. Through an enthralling narrative, she tackles themes such as surveillance, freedom, and resistance. Fyre provocatively questions what it means to be free in a world where every action is monitored and every rebellion quashed. This contemporary relevance is embroidered seamlessly into the plot, engaging readers with its pertinence.

The plot itself is a rollercoaster, with twists aplenty that keep surprise and suspense consistently dialed high. The pacing is judicious; rapid when the tension is thick and more measured when delving deep into character development. Fyre’s skill in plotting ensures that the energy never sags, and the stakes continually escalate towards a climax that is both satisfying and thought-provoking. However, it is worth noting that the dense plot and complex themes might not resonate with everyone, particularly those looking for a lighter read.

In terms of writing style, Montana Fyre exhibits a balanced blend of straightforward narration and rich, metaphor-laden prose. This duality makes her writing accessible while also rewarding more attentive readers with deeper symbolic layers. Her dialogue is sharp and often laden with emotional weight, capturing the strained interactions of people living on the edge. It’s this deft handling of human emotions and interactions that truly breathes life into the narrative, providing it a grounded, poignant edge.

Moreover, the world-building in They Will Burn deserves a special mention. Fyre doesn’t just create a setting; she engulfs the reader in it. The oppressive atmosphere of The Directorate's regime is almost palpable, with technological innovations both fascinating and terrifying. The meticulous attention to detail in constructing this world pays off by immersively transporting the reader, which is arguably one of the novel’s biggest strengths.

Nevertheless, no book is without its flaws. The intricate plot might overwhelm at times, and some twists may seem predictable to seasoned readers of the genre. Additionally, the ending, while effective, might not sit well with everyone, depending on their expectations for closure versus open-endedness.

In conclusion, They Will Burn by Montana Fyre is a darkly enthralling debut that successfully marries a thought-provoking narrative with a visceral, emotional journey. Its exploration of themes relevant to our contemporary landscape makes it not just a compelling read but also an important one. Fans of dystopian narratives that challenge the status quo will find this novel a formidable addition to their shelves. Montana Fyre, with her bold narrative voice and insightful world-building, is certainly an author to watch. As Elara’s journey unfolds, one can’t help but root for her, fear for her, and ultimately, burn with her.
