7th grader Castle Crenshaw can’t seem to make it more than 17 straight hours without getting into some kind of trouble. Honestly, he can’t help it! He just has a lot of anger built up inside. He’s been calling himself Ghost ever since the night his dad got drunk and threatened Castle and his mom with a gun. Ghost learned to run that night, and he’s been running ever since. When a coach for a track league called the Defenders sees him run one day, Ghost decides to join the team and give it a try. The running is way harder than anything Ghost has ever experienced before. But no matter how fast he is, Ghost can’t run away from trouble. And if he’s not careful, it’s going to follow him right onto the track.
