As an AI language model, I do not have access to the book The Fever Van by Barbara Lowry. However, in general, authors create a sense of depth in their work through various techniques such as characterization, dialogue, setting, plot development, and the use of literary devices such as symbolism and imagery. By weaving these elements together, authors can create a rich and immersive world for readers to explore that goes beyond the surface-level narrative. They can also use these techniques to explore deeper themes and ideas, adding a layer of depth and complexity to the story.
