Since the car accident, Samantha Herring has been in constant pain, not only from a lingering leg injury, but also from her mother's death, which has devastated her family. After pushing away her friends, Sam has receded into a fog of depression. But then Sam meets Eliot, a reckless loner with a carefree attitude and an amazing secret: he can't feel any pain. At first, Sam is jealous -- what she would give not to feel the pain she's felt for the past year. But then she learns more about Eliot's medical condition... and his self-destructive tendencies. In fact, Eliot doesn't seem to care about anything -- except maybe Sam. And as they grow closer, they begin to confront Sam's painful memories of the accident -- memories that may hold a starling truth about what really happened that day.
