Seanan McGuire’s Installment Immortality is a captivating addition to the InCryptid series, a saga that has consistently blended urban fantasy with elements of family drama and supernatural intrigue. This installment continues to explore the rich tapestry of the Price family’s legacy while introducing new dimensions to the series through the character of Mary Dunlavy, a ghostly nanny with a mission that transcends the boundaries of life and death.

At the heart of Installment Immortality is Mary Dunlavy, a character who has been a steadfast presence in the Price family for generations. Her evolution from a background figure to a central protagonist is handled with deftness and care. McGuire skillfully fleshes out Mary’s character, providing her with a depth that resonates with readers. Her journey from a caretaker to an active agent of change is both compelling and poignant. Mary’s new role as an employee of the anima mundi, Earth’s living soul, adds a fascinating layer to her character, highlighting her resilience and adaptability.

The novel’s plot is a whirlwind adventure, as promised in the blurb. McGuire expertly balances action with introspection, creating a narrative that is both thrilling and thought-provoking. The mission to stop the Covenant of St. George from imprisoning America’s ghosts serves as a backdrop for exploring themes of freedom, duty, and the complexities of the afterlife. The road trip element of the story adds a dynamic quality, allowing for character development and interaction that feels organic and engaging.

Mary’s companions, Elsie and Arthur, are equally well-developed. Their grief over the loss of their mother is portrayed with sensitivity, adding emotional depth to the story. Elsie’s mourning and Arthur’s gradual collapse are depicted with authenticity, making their journey alongside Mary not just a physical one, but an emotional and psychological exploration as well. McGuire’s ability to weave these personal narratives into the larger plot is a testament to her skill as a storyteller.

One of the standout aspects of Installment Immortality is its exploration of the concept of the anima mundi. This manifestation of Earth’s soul is a unique and intriguing addition to the series’ mythology. It raises questions about the interconnectedness of life and the responsibilities that come with power. Mary’s interactions with the anima mundi are some of the most thought-provoking moments in the book, prompting readers to consider the broader implications of her mission.

McGuire’s writing style is as engaging as ever, with a blend of humor, wit, and poignancy that keeps readers invested from start to finish. Her ability to create vivid, immersive settings is evident in the descriptions of Worcester, Massachusetts, and the various supernatural elements that populate the story. The pacing is well-executed, with a balance of action and quieter moments that allow for reflection and character growth.

In comparison to other works in the urban fantasy genre, Installment Immortality stands out for its focus on family dynamics and the exploration of life beyond death. While it shares similarities with series like Jim Butcher’s The Dresden Files in terms of its supernatural elements and action-packed narrative, McGuire’s emphasis on character development and emotional depth sets it apart. The InCryptid series, and this installment in particular, offers a fresh perspective on the genre, blending traditional fantasy tropes with contemporary themes.

Overall, Installment Immortality is a worthy addition to the InCryptid series, offering both long-time fans and new readers a rich, engaging story that is both entertaining and thought-provoking. Seanan McGuire continues to demonstrate her mastery of the urban fantasy genre, crafting a tale that is as much about the human (and ghostly) experience as it is about supernatural adventure. Mary Dunlavy’s journey is one that will resonate with readers, leaving them eagerly anticipating the next chapter in this captivating series.

For those interested in exploring the world of the InCryptid series, Installment Immortality is a must-read, offering a perfect blend of action, emotion, and supernatural intrigue that is sure to captivate and inspire.
