Donna McDonald's 40 Ways to Say Goodbye is a captivating blend of fantasy, humor, and emotional depth, offering readers a unique take on the complexities of relationships and personal redemption. The novel centers around Aran O’Malley, a nearly forty-year-old witch from the lineage of the Tuatha de Danann, who is navigating the tumultuous waters of post-divorce life while dealing with the supernatural intricacies of her world.

One of the most compelling aspects of the book is its exploration of the theme of identity. Aran's journey is not just about severing ties with her ex-husband, Jack Derringer, but also about reclaiming her own identity. Her struggle to revert from Aran Derringer back to Aran O’Malley is symbolic of her desire to shed the past and embrace her true self. This theme is universally relatable, as many readers will recognize the challenge of rediscovering oneself after a significant life change.

The character development in 40 Ways to Say Goodbye is particularly noteworthy. Aran is a well-rounded protagonist whose strength and vulnerability make her both relatable and admirable. Her relationship with Connlander of the Fir Bolg, her hereditary familiar, adds depth to her character. Conn is not just a magical companion but a true friend and confidant, providing emotional support and comic relief throughout the narrative. This dynamic is reminiscent of the familiar bonds seen in other fantasy works, such as Philip Pullman's His Dark Materials series, where the familiar is an extension of the protagonist's soul.

Jack Derringer, Aran's ex-husband, serves as a complex antagonist. His betrayal and the subsequent fallout are central to the plot, driving Aran's actions and decisions. McDonald skillfully portrays Jack as a multifaceted character, avoiding the trap of making him a one-dimensional villain. Instead, his motivations and actions are explored in a way that adds depth to the story, making the reader question the nature of betrayal and forgiveness.

The novel's setting is richly imagined, blending elements of Irish mythology with contemporary fantasy. McDonald's use of the Tuatha de Danann and the Fir Bolg adds an authentic layer of mythological intrigue, grounding the fantastical elements in a well-researched cultural context. This attention to detail enhances the world-building, making it immersive and believable.

Humor is another standout feature of 40 Ways to Say Goodbye. McDonald's witty dialogue and clever situations provide levity amidst the more serious themes of the book. Aran's sarcastic inner monologue and her interactions with Conn are particularly entertaining, offering a refreshing contrast to the darker elements of the story. This balance of humor and drama is reminiscent of works by authors like Terry Pratchett, who masterfully blend the two to create engaging narratives.

Despite its fantastical elements, the novel tackles real-world issues such as the struggle for independence, the complexities of co-parenting, and the quest for personal redemption. Aran's determination to clear her name and secure a magical divorce from Jack is a metaphor for the broader human desire to move on from past mistakes and find peace. Her journey is one of empowerment, as she learns to stand up for herself and take control of her destiny.

Overall, 40 Ways to Say Goodbye is a compelling read that will appeal to fans of fantasy and those who enjoy stories of personal growth and empowerment. Donna McDonald has crafted a narrative that is both entertaining and thought-provoking, with characters that linger in the reader's mind long after the final page is turned. The novel's blend of humor, mythology, and emotional depth makes it a standout in the fantasy genre, offering a fresh perspective on the age-old themes of love, loss, and self-discovery.

For readers who appreciate a strong female protagonist and a story that seamlessly weaves together the magical and the mundane, 40 Ways to Say Goodbye is a must-read. Its engaging plot, well-developed characters, and rich world-building make it a book that is sure to resonate with a wide audience.
