The novel is filled with conflicts, as any compelling work must be. The premise of the novel is that the main character, Carl, sells his soul to the devil for basketball success. Of course, this is the main conflict in the novel. However, Carl also has other problems, namely his relationship with his father and problems at school.
Carl is desperate for basketball success, partially due to his high-pressure father. He practices quite hard, and even practices alone. However, the internal conflict caused by the juxtaposition between his ambitions and reality eventually lead him to sell his soul to the devil, which he regrets at times. Part of the reason for him selling his soul to the devil is his desire to move to a different school and make the basketball team, which he believes will help him fit in.
