Strongest Souls by Riley Onyx is a gripping tale that plunges readers into a dark and twisted world where power, loyalty, and the struggle for survival intertwine in a captivating narrative. Set against the backdrop of the ominous castle in Under, the story unfolds with a sense of urgency and dread, as the protagonist finds herself ensnared in a web of manipulation and danger orchestrated by the ruthless Queen of Under.

The blurb sets the stage for a story that is anything but a fairy tale. The Queen, a figure of brutality and terror, has seized control through sheer force, and her insatiable thirst for power leads her to seek out the protagonist, who becomes a pawn in her sinister game. This premise introduces readers to a world where the stakes are high, and the consequences of failure are dire. The protagonist's struggle to escape the clutches of the Queen is not just a physical battle; it is a fight for her very soul and the souls of those she loves.

One of the most compelling aspects of Strongest Souls is the character development. The protagonist is not merely a damsel in distress; she is a fierce and determined individual who is willing to fight for her pack, showcasing her resilience and strength. As the narrative progresses, readers witness her evolution from a captive to a leader, as she navigates the treacherous landscape of Under and confronts the Queen's guards. Onyx skillfully crafts her character, imbuing her with depth and complexity that makes her relatable and inspiring.

The supporting characters are equally well-developed, each with their own struggles and motivations. The pack, which serves as both a source of strength and a burden, adds layers to the story. Their loyalty and willingness to fight for the protagonist highlight the themes of friendship and sacrifice, while also illustrating the toll that constant conflict takes on their souls. As the fighting escalates, the glimmers of their spirits begin to fade, creating a palpable sense of urgency that propels the narrative forward.

The theme of sacrifice resonates throughout the book, as characters are faced with difficult choices that test their loyalty and resolve. Onyx does an excellent job of exploring the emotional weight of these decisions, making readers question what they would be willing to sacrifice for those they love. This theme is particularly poignant in the context of the protagonist's relationship with her pack, as their fates are intertwined, and her determination to save them drives the plot.

Another significant theme is the exploration of power dynamics and the corrupting influence of authority. The Queen of Under embodies the archetype of a tyrant, ruling through fear and brutality. Her character serves as a stark reminder of how power can corrupt even the most noble intentions. Onyx's portrayal of the Queen is nuanced; she is not merely a villain but a complex character shaped by her own experiences and desires. This complexity adds depth to the narrative, inviting readers to ponder the nature of power and its impact on individuals and relationships.

The world-building in Strongest Souls is richly imagined, with vivid descriptions that bring the dark and foreboding landscape of Under to life. Onyx's attention to detail creates an immersive experience, allowing readers to feel the oppressive atmosphere of the castle and the desperation of the characters. The setting itself becomes a character in its own right, influencing the actions and decisions of the protagonists as they navigate its dangers.

Onyx's writing style is engaging and fluid, making it easy for readers to become absorbed in the story. The pacing is well-balanced, with moments of intense action interspersed with quieter, reflective scenes that allow for character development and emotional depth. This balance keeps readers on the edge of their seats while also providing them with the opportunity to connect with the characters on a deeper level.

In comparison to other works in the genre, Strongest Souls stands out for its unique blend of fantasy and psychological depth. Readers who enjoy the works of authors like Sarah J. Maas or Jennifer L. Armentrout will find much to appreciate in Onyx's storytelling. The themes of loyalty, sacrifice, and the struggle against tyranny resonate with those familiar with the darker aspects of fantasy literature, while the strong character arcs and emotional stakes elevate the narrative beyond typical genre conventions.

Overall, Strongest Souls is a powerful and thought-provoking read that captivates from the first page to the last. Riley Onyx has crafted a tale that is not only entertaining but also rich in themes that resonate with readers on multiple levels. The journey of the protagonist and her pack is one of resilience, courage, and the enduring power of love and friendship in the face of overwhelming darkness. This book is a must-read for anyone who enjoys a gripping fantasy with heart and depth.
