The continuity of the Monster High book series is vastly different from the other Monster High continuities. Rather than Frankie Stein, the role of protagonist is shared between Frankie and the book-exclusive character Melody Carver, with a balance tilted in Melody's favor. Each of the books tells an ongoing story through the eyes of one selected character. In the case of the first book, it's Frankie Stein, the second is about Cleo de Nile, the third about Clawdeen Wolf, and the fourth one about Draculaura. The thirteenth chapters of all four books are missing from those books and were released on special occasions. The thirteenth chapters focus on Ghoulia Yelps.
