What Makes an Alien a Dad? by Marina Simcoe is a captivating exploration of family, identity, and unexpected paternal bonds in a fantastical interstellar setting. This science fiction novel digs deep into the dynamics of fatherhood through the lens of alien characters, challenging the reader's perceptions of what truly constitutes a parent or a father figure, especially in circumstances beyond the mundane confines of Earth.

The story revolves around a humanoid alien, Toren, who discovers that his experimental contribution to Earth many years ago inadvertently resulted in the birth of a human-alien hybrid child, Lily. Faced with the reality of his unsuspected fatherhood, Toren grapples with a rush of unfamiliar, paternal instincts and an overwhelming sense of responsibility towards Lily. Simcoe skilfully presents Toren’s emotional journey, delving into the complexities of taking on a parental role when the very concept of family is alien.

Simcoe’s portrayal of Toren is nuanced and deeply personal. From the initial shock to the evolving acceptance and fierce protective affection towards his daughter, Toren’s transformation is both believable and poignant. The author provides a detailed backdrop of Toren’s own cultural understanding of family and parenthood, which contrasts starkly with human traditions. This not only adds depth to his character but also poses philosophical queries about the essence of parental love and commitment across different species and cultures. Toren's interaction with Lily, who is a precocious and endearing child, further smooths his edges and humanizes him in ways that he never expected.

The sci-fi elements in the novel are imaginatively crafted, with Simcoe integrating advanced technologies and intergalactic societal structures without overwhelming the core story of father-daughter relationship. The depiction of different planets and alien technologies is vivid and serves to enhance the narrative rather than detract from the emotional core. The author uses these elements to broaden the setting, crafting a rich tapestry of interstellar life that reflects upon and enriches the central themes of family and identity.

The secondary characters add a layer of complexity and charm to the plot. For instance, the cautious but supportive relationship between Toren and his sibling adds another dimension to the alien’s understanding of relationships and indirectly helps him in his journey of self-discovery as a father. Each character is well thought out and contributes to the overall narrative rhythm, helping to push the plot forward and deepen the main themes.

Simcoe also navigates the potential pitfalls of a human-alien relationship with tact and sensitivity. The narrative avoids exoticizing or oversimplifying Toren’s alien nature. Rather, it celebrates the differences in thinking and lifestyle, suggesting that love and care are universal values that transcend species. This thematic depth is where Simcoe truly excels, enveloping her readers in a story that is as much about finding connection and common ground as it is about the sci-fi trope of first contact.

Stylistically, Simcoe maintains a smooth and engaging prose that balances dialogue with descriptive passages effectively. Her ability to conjure powerful emotional moments without slipping into melodrama is noteworthy and makes for a compelling read. The pacing is deliberate, with each chapter building on the last in both tension and emotional stakes, driving towards a climax that is both satisfying and thought-provoking.

On the whole, What Makes an Alien a Dad? is an intriguing blend of science fiction and deep human (and non-human) drama that tackles complex emotions with sensitivity and insight. Marina Simcoe has crafted a novel that not only provides a thrilling interstellar adventure but also a heartwarming meditation on the bonds of parenthood, seen through a fresh, unconventional lens. For readers looking for a story that combines robust sci-fi world-building with genuine human connection, this book is a delightful and unique read.

In conclusion, Marina Simcoe’s What Makes an Alien a Dad? is a resonant and innovative addition to the genre of science fiction that probably will appeal beyond its immediate audience to anyone interested in the narratives of personal and relational discovery. The universality of its themes, couched in the specificity of its intergalactic setting, makes it a compelling, and ultimately uplifting, read.
