Penelope Mars' Bred By Fafnir is a provocative exploration of survival, identity, and unexpected intimacy set against the backdrop of a dystopian universe where humanity is at the mercy of more advanced alien species. The novel's premise is both intriguing and unsettling, offering a narrative that challenges the reader to consider the lengths to which individuals will go to ensure their survival and the survival of their loved ones.

The story is set in a future where humanity is scattered across the stars, living in poverty and desperation. The protagonist, a young woman faced with dire circumstances, finds herself with limited options. Her decision to become a surrogate through the Solar Breeding Agency is a poignant reflection of the harsh realities faced by those living on the fringes of society. Mars does an excellent job of painting a vivid picture of this universe, one where humans are seen as commodities, valued for their ability to provide cheap labor, entertainment, and, most disturbingly, their capacity for reproduction.

At the heart of the novel is the relationship between the protagonist and Fafnir, the alien to whom she is paired. Fafnir is a complex character, a berserker alien known for his violent tendencies and rumored to suffer from war madness. The initial portrayal of Fafnir is one of danger and unpredictability, yet as the story unfolds, Mars skillfully peels back the layers of his character, revealing a depth and vulnerability that is both surprising and compelling. This character development is one of the novel's strongest points, as it challenges the reader's initial perceptions and encourages a deeper understanding of what it means to be alien, both literally and metaphorically.

The themes of power dynamics and consent are central to the narrative. The protagonist's journey is one of empowerment, as she navigates the complexities of her relationship with Fafnir and the broader societal structures that seek to control her. Mars handles these themes with sensitivity and nuance, creating a narrative that is both thought-provoking and emotionally resonant. The exploration of consent, in particular, is handled with care, as the protagonist grapples with her own desires and the expectations placed upon her by the society she inhabits.

One of the most intriguing aspects of Bred By Fafnir is the way it subverts traditional romance tropes. The relationship between the protagonist and Fafnir is not one of immediate attraction or love, but rather one that develops through mutual understanding and respect. This slow burn is a refreshing departure from the often formulaic portrayals of romance in science fiction and fantasy, and it adds a layer of authenticity to the characters' interactions. The novel also explores the idea of found family, as the protagonist and Fafnir form a bond that transcends their initial transactional relationship.

In terms of world-building, Mars excels at creating a universe that is both expansive and intimate. The societal structures and alien cultures are richly detailed, providing a backdrop that enhances the narrative without overwhelming it. The author's attention to detail is evident in the way she describes the various alien species and their customs, adding depth and texture to the story. This world-building is complemented by Mars' evocative prose, which brings the universe to life in vivid detail.

Comparatively, Bred By Fafnir shares thematic similarities with works such as The Handmaid's Tale by Margaret Atwood, particularly in its exploration of women's roles in a dystopian society. However, Mars' novel stands out for its unique blend of science fiction and romance, offering a narrative that is both engaging and thought-provoking. The novel also bears resemblance to Ruby Dixon's Ice Planet Barbarians series, which similarly explores the dynamics of human-alien relationships, though Mars' work is distinguished by its darker, more introspective tone.

Overall, Bred By Fafnir is a compelling and thought-provoking read that challenges the reader to consider the complexities of identity, power, and intimacy in a universe where humanity is both marginalized and commodified. Mars' skillful character development and nuanced exploration of difficult themes make this novel a standout in the genre, offering a narrative that is both entertaining and deeply resonant. For readers seeking a science fiction romance that defies convention and offers a fresh perspective on familiar themes, Bred By Fafnir is a must-read.
