Form
''Cathy’s Key'' follows the tradition established by its predecessor in presenting the story in a radically innovative way. Similar to a graphic novel, the text of the story is accompanied by hand-drawn images (created by illustrator Cathy Briggs), yet ''Cathy’s Key'' also contains a cache of objects that are related to the plot. For instance, the “evidence package” in ''Cathy’s Book'' contains artifacts such as a wedding invitation, a menu from a restaurant, various letters, a napkin, a death certificate, and four pieces of a ripped photo, among other items.Scholarly criticism
The scholarly criticism for the text has tended to focus on its unique form and the opportunities that presents. For instance, Motoko Rich wrote an article in ''The New York Times'' entitled “Product Placement Deals Make Leap From Film to Books” (2006) that discussed how Stewart had incorporated a lip gloss made by Cover Girl in exchange for free advertising on their online website. Other writers view such a relationship as overly commercialized and effectively commodifying literature, and have written about the effect that this may have on impressionable teen readers and teen writers. Still more critics have positively focused on the text as adapting digital age characteristics to remain relevant in an increasingly technology-centered age. The term “dynamic hybrid” was coined to describe Stewart’s multimedia (phone numbers, web addresses etc.) approach to literature, while other scholars see the possibility for the text to become associated with gaming networks. Indeed, some even go so far as to classify the work as an ARG, or alternate reality game.Book reviews
The reviews for ''Cathy’s Key'' praise the spunkiness of the heroine and its multi-media impact. However, a few readers critiqued the work as having a plot that sometimes seemed disorganized and hard to follow. The book is especially recommended for fans of manga, gaming followers, and reluctant readers, and is categorized within the YA or young adult section of libraries.{{cite journal, title=Cathy's Key, journal=Kirkus Reviews, date=15 April 2008References
