Why did the MacGill used a Chinese fortune cookie in the book everlost?

In "Everlost" by Neal Shusterman, the MacGill uses a Chinese fortune cookie to symbolize the unpredictability of fate and the importance of choice. The cookie's message serves as a reminder to the characters that their paths in the afterlife are shaped by their decisions and actions. This moment emphasizes the theme of self-discovery and the influence of seemingly small events on larger outcomes.
