Caitriona Drexler's Once Upon an Apocalypse is a gripping tale that seamlessly blends the elements of a post-apocalyptic thriller with the emotional depth of a character-driven narrative. The story centers around Lori, a protagonist whose journey from despair to hope is both harrowing and inspiring. As the blurb suggests, Lori's world is turned upside down when she finds herself in a desolate landscape, battling not only the undead but also the remnants of humanity's darker side.

One of the most compelling aspects of Drexler's novel is its exploration of human resilience and the indomitable spirit that drives individuals to survive against all odds. Lori's character is a testament to this theme. Initially introduced as a prisoner subjected to cruel experiments, she emerges as a powerful symbol of resistance and hope. Her transformation from a victim to a warrior is both believable and empowering, making her a character that readers can root for.

The setting of The Valley, a survivor camp hidden amidst the farmlands of Central Pennsylvania, provides a stark contrast to the chaos of the outside world. This community, with its emphasis on maintaining humanity, history, and culture, offers a glimmer of hope and a chance for a new beginning. Drexler skillfully uses The Valley as a microcosm of what society could be, even in the face of an apocalypse. It is a place where Lori can finally dream again, and perhaps, find love.

However, the novel does not shy away from the complexities of rebuilding a society. Lori's realization that "sitting around playing house" is not for her adds depth to her character. Her special abilities, a result of the experiments she endured, become a crucial part of her identity. Drexler effectively uses these abilities to explore themes of power and responsibility. Lori's struggle to prove herself to her new friends and to Amos, the stranger who saved her, is a poignant reminder of the challenges that come with newfound power.

Amos, as a character, serves as both a savior and a catalyst for Lori's transformation. His introduction into the narrative brings a sense of stability and hope, yet he is not without his own complexities. The dynamic between Lori and Amos is one of mutual respect and understanding, and their relationship is a central pillar of the story. Drexler's portrayal of their evolving bond is nuanced and adds an emotional layer to the narrative.

In terms of thematic exploration, Once Upon an Apocalypse delves into the nature of humanity in the face of extinction. The presence of zombies, while a staple of the genre, is used more as a backdrop to explore deeper questions about what it means to be human. The novel raises important questions about morality, survival, and the lengths to which individuals will go to protect those they love.

Comparatively, Drexler's work can be likened to other post-apocalyptic narratives such as Cormac McCarthy's The Road or Emily St. John Mandel's Station Eleven. However, Drexler's focus on character development and the emotional journey of her protagonist sets her work apart. While McCarthy's novel is stark and unrelenting in its portrayal of a desolate world, and Mandel's work is more reflective and philosophical, Drexler strikes a balance between action and introspection.

The pacing of the novel is well-executed, with moments of intense action interspersed with quieter, introspective scenes. This balance keeps the reader engaged while allowing for character development and thematic exploration. Drexler's writing style is both accessible and evocative, painting vivid pictures of the post-apocalyptic landscape while delving into the inner workings of her characters.

Overall, Once Upon an Apocalypse is a compelling read that offers both thrills and emotional depth. Caitriona Drexler has crafted a story that is not only about survival but also about the enduring power of hope and the human spirit. Lori's journey is one that will resonate with readers, leaving them with much to ponder about the nature of humanity and the world we live in.

For those who enjoy post-apocalyptic tales with strong character arcs and thought-provoking themes, Once Upon an Apocalypse is a must-read. It is a story that challenges the reader to consider what they would do in the face of an apocalypse and what it truly means to be human.
