Many reviewers were so impressed that they immediately sought out the next books in the series, often recommending it as a delightful introduction to the author's work.

Despite its strengths, some readers found aspects of the book less appealing. A common point of contention was the portrayal of certain characters, particularly the older sister, Gwendolen, who is frequently described as selfish, cruel, and even "horrid," which some found difficult to fully engage with. The younger brother, Cat, was occasionally seen as too passive or meek, leading to frustration for some readers. A significant criticism revolved around the plot's reliance on a lack of communication between characters, with many feeling that much of the tension could have been avoided if information had been shared, making some of the conflict feel fabricated. Additionally, some reviewers were disappointed by the magic system's lack of explicit rules or consistency. The book also contains elements that show its age, including instances of casual racism, fatphobia, and scenes of physical punishment, which some modern readers found problematic or uncomfortable.

Overall, this book stands as a solid and intriguing entry into children's fantasy, offering a captivating world and a story that, despite its minor flaws, leaves a lasting impression. While not an epic adventure in the traditional sense, its unique tone and subtle complexities are appreciated by many. It comes highly recommended for fans of children's fantasy, particularly those who enjoy imaginative magical worlds and character-driven stories, with several reviewers noting its appeal to readers who appreciate the Harry Potter series. However, those looking for a clearly defined magic system, overt heroism, or who are sensitive to dated social commentary and instances of physical discipline might find certain aspects challenging. It is best suited for readers who enjoy nuanced character dynamics and a narrative that gradually unfolds its deeper implications.
