When a guy in his class looks at him funny, Diego punches him in the face, and ends up on probation. At first he wants nothing to do with his probation officer. But as Diego starts to open up, he begins to realize that Mr. Vidas is the first person in his life who ever really wanted to listen to him. With Vidas's help, Diego begins to make real progress in controlling his anger. He even opens up enough to tell Vidas about the shark tooth that his stepfather gave him that he uses to cut himself. But only if Diego can find the courage to trust Vidas with the darkest secrets from his past will he be able to heal completely.In this bold story of a boy trying to grow beyond a painful past, award-winning author Alex Sanchez calls upon his personal experience as a probation officer to reveal the complexities of one of his most genuinely realized characters to date.
