Sometimes one mistake can change everything. Emily doesn't know why she froze. Or why Lucas did too. Afterward, she thought of different ways to rationalize it. But the truth is, they could have helped Belinda, and they didn't. It's a mistake they'll both have to live with. Emily and Lucas's punishment is community service at a center for people with disabilities. People like Belinda. Soon they feel like maybe they're starting to make a real difference. But when Belinda returns to school, Emily and Lucas have to figure out if they can do anything that will actually help the one person they hurt most.
