Cathy's Book

Cathy's Book is an interactive young adult novel that combines traditional storytelling with real-world elements.

After discovering a mysterious mark on her arm, Cathy and her best friend Emma become entangled in a complex mystery involving Chinese mythology and immortality.

These multimedia components allow readers to participate in solving the mystery alongside the main characters. The story explores themes of friendship, truth, and the blurred lines between reality and fiction, creating an experience that challenges traditional boundaries between reader and narrative.

Readers found this interactive mystery novel engaging but uneven. The multimedia elements - phone numbers to call, websites to visit, and physical evidence packets - created an immersive experience that many readers enjoyed exploring alongside the main story. Liked: - Detailed artwork and realistic artifacts - Phone numbers and websites that worked - Creative format and presentation - Relatable teenage protagonist voice Disliked: - Plot described as thin and predictable - Story feels secondary to the multimedia gimmick - Some found the protagonist annoying - Interactive elements dated quickly as websites/numbers expired "The extras make up for the basic plot" was a common sentiment in reviews. Several readers noted they spent more time examining the supplementary materials than reading the actual text.
