After Will's brother Shawn was shot and killed, Will knows that the rules of his neighborhood dictate that he must exact revenge on his brother's murderer. As Will takes the elevator down to complete his deadly task, a victim of gun violence from his past boards the elevator at each floor. Reynolds, who might be YA literature's modern-day Shakespeare, crafts a masterful verse novel that readers will read quickly but ponder deeply, especially after the powerful final line.
