One theme in Rumble FIsh is that life isn't fair. This is because Rusty James was dealt a bad hand of cards to start out with. For example, his mother was never around.
Abandonment is also a theme in Rumble Fish. This is because Rusty James parents left him alone for three days. This is why he struggles with being alone.
One character trait of Rusty James is that he liked to relive the past. He was alwasy talking about past gang fights.
Rusty James didn't plan for the future. He did not plan for his future health or saftey because he drank acohol.
I thought if the book was a tad bit longer it would have been better. It left you with some unanswered questions. An example of this is what happened to Rusy James' mother? Did Rusty ever go to see her?
