the gun was about tyray wanting revange because othe new kid darrell beat him up in front of the whole school. until he hand it so he talk to a guy that was selling a gun so he bought the gun.
i connect this to peer presure because he bought the gun and that could be peer presure. another is violance because this happen almost every where.
i gave this book a five star because i like how the character acts and how the plot is.
