Listing all of the settings is going to be a bit tough. There might be some really minor locations that a reader might consider a setting that other readers would not consider a setting location. For example, at one point in the book, Roy is riding in a school bus. I would like to focus on the main settings of the book.
The broad setting is Coconut Grove, Florida. The story then takes place within smaller, more specific locations within that city. Roy goes to school at Trace Middle School. His home is also a setting location throughout the book. A nearby forest is another location, and this is where Mullet Fingers lives. A fourth and final main location is the construction site where the new pancake house-style restaurant is being built.
