The first is that of the Monkey King. It is from a Chinese legend about a monkey god who wants to prove to the other gods in heaven that he is more than just a monkey. Unfortunately, his pride gets the better of him.
The second is about a Chinese American boy named Jin Wang. When we first meet him, he is a young boy who has just arrived at a new school where he is the only Chinese-American kid. He has to deal with racism and loneliness at first as he tries to fit in.
The third is about a popular kid named Danny. Once a year, he gets a visit from his extremely embarrassing Chinese cousin Chin-Kee. Chin-Kee is a character made up of a shocking exaggerated set of negative Chinese stereotypes. Danny is so embarrassed when he visits that he has changed high schools every year after his cousin visits.
Though these three stories seem really unrelated at first, they come together in surprising ways by the end of the book.
