Similar to the "Goosebumps" series, the characters change in each book, although some characters still live on and are mentioned (or show up) multiple times. Some of the previous novel plots are also mentioned in later books, and some characters appear in multiple stories (for instance Cory Brooks, hero of "The New Girl" is mentioned and shows up several times during the later novels). The plot for the books occur between the late 1980s and early 1990s, although multiple novels occur within the same chronological year they take place. All books released are also released in the Shadyside chronological timeline it occurs.
