Castle in the Air (World of Howl)

Many readers found the book to be a highly readable, fun, and whimsical fantasy adventure. Reviewers praised the author's distinctive writing style, which offers vivid imagery and descriptive prose that brings the new setting to life. The story introduces an Aladdin-esque world rich with magic carpets, genies, djinns, and sultans, successfully expanding the universe established in its predecessor with unique customs and charming, often humorous, dialogue. The plot is described as intricate and well-elaborated, featuring engaging twists that maintain a steady pace. While primarily focusing on new characters and an Arabian-inspired journey, the narrative also eventually connects with familiar elements and beloved characters from the previous book, a reveal that many fans found delightful.

Despite its strengths, the book also drew considerable criticism for several problematic elements. Many reviewers found the new main character, Abdullah, to be unlikable, shallow, and at times, sexist in his attitudes towards women and beauty. Female characters, including the love interest, are frequently described as weakly written, lacking agency, and primarily defined by their appearance or domestic roles, which led to strong accusations of sexism and women being overshadowed by male characters. Reviewers also noted instances of fat-shaming and the use of what some perceived as problematic Middle Eastern stereotypes, suggesting the book has not aged well. Additionally, some felt the plot's resolution was rushed or chaotic, and the central romance lacked depth due to its "insta-love" development. For many expecting a more direct continuation, the limited presence of characters from the first book until later in the narrative was a source of disappointment.

Overall, opinions on the book are mixed, with many acknowledging its imaginative qualities but also its significant flaws, especially when compared to its highly acclaimed predecessor. While some found it equally or even more enjoyable than the first book, others were profoundly disappointed. It is generally recommended for middle-grade and young adult readers, as well as anyone who enjoys whimsical children's literature. However, potential readers should be aware of the problematic themes discussed, particularly regarding character portrayals and cultural stereotypes, and some suggest it might be best read with a critical eye or skipped entirely if seeking a direct and seamless continuation of the first book's narrative and character dynamics.
