Jax Calder's The Unlikely Spare is a delightful blend of royal intrigue, romance, and suspense, offering readers a fresh take on the classic "prince and bodyguard" trope. This novel stands out not only for its engaging plot but also for its nuanced exploration of identity, duty, and personal growth.

At the heart of the story is Prince Nicholas, the so-called "spare" to the heir of the British throne. Nicholas is a character who initially appears to be the quintessential royal playboy, using his charm and wit as a shield against the expectations and constraints of his royal life. However, as the narrative unfolds, Calder skillfully peels back the layers of Nicholas's character, revealing a man who is deeply introspective and increasingly aware of the historical and cultural implications of his position. This journey of self-discovery is one of the novel's most compelling aspects, as Nicholas grapples with the uncomfortable truths about colonialism and his family's legacy.

In stark contrast to Nicholas is Eoin O’Connell, the brooding and enigmatic undercover agent tasked with protecting the prince. Eoin's backstory is rich and textured, providing a gritty counterpoint to Nicholas's privileged upbringing. Having clawed his way up from the slums of Ireland, Eoin is a man driven by duty and a desire to prove himself. His initial disdain for Nicholas's seemingly carefree attitude is palpable, yet as the story progresses, Eoin's perspective shifts, and he begins to see the depth and complexity beneath Nicholas's façade.

The chemistry between Nicholas and Eoin is electric, and Calder expertly navigates the tension between duty and desire. Their relationship is a slow burn, filled with witty banter and moments of vulnerability that make their eventual romance both believable and satisfying. The dynamic between the two characters is reminiscent of other popular romantic suspense novels, such as those by authors like Josh Lanyon and Tal Bauer, where the protagonists must balance their professional responsibilities with their personal feelings.

One of the novel's strengths is its ability to seamlessly blend humor with suspense. The comedic elements, such as koala cuddling sessions and didgeridoo lessons, provide levity and charm, while the underlying threat to Nicholas's life adds a layer of tension that keeps readers on the edge of their seats. Calder's writing is sharp and witty, with dialogue that sparkles and scenes that are vividly described, making the settings of Australia and New Zealand come alive.

In terms of themes, The Unlikely Spare delves into the idea of identity and the roles we are expected to play. Both Nicholas and Eoin are characters who are defined by their positions—one by birth and the other by choice—and the novel explores how they navigate these roles while staying true to themselves. The theme of personal growth is also prominent, as both characters must confront their own biases and insecurities to find happiness and fulfillment.

Calder also tackles the theme of privilege and responsibility, particularly through Nicholas's character arc. The novel does not shy away from addressing the historical injustices associated with the British monarchy, and Nicholas's journey towards understanding and acknowledging these issues adds depth to his character and the story as a whole.

Overall, The Unlikely Spare is a captivating read that offers a perfect blend of romance, humor, and suspense. Jax Calder has crafted a story that is both entertaining and thought-provoking, with characters that are well-developed and relatable. The novel's exploration of identity, duty, and personal growth resonates long after the final page is turned, making it a standout in the genre.

For readers who enjoy romantic suspense with a royal twist, The Unlikely Spare is a must-read. It is a testament to Calder's skill as a storyteller that the novel manages to be both a lighthearted romantic comedy and a poignant exploration of deeper themes. Whether you're a fan of royal romances or simply looking for a well-crafted story with engaging characters, this book is sure to delight and entertain.
