Nineteen-year-old Cromwell Dean is the rising star of electronic dance music. Thousands of people adore him. But no one knows him. No one sees the color of his heart. Until the girl in the purple dress. She sees through the walls he has built to the empty darkness within. When Cromwell leaves behind the gray skies of England to study music in the South Carolina heat, the last thing he expects is to see her again. And he certainly doesn't expect that she'll stay in his head like a song on repeat.

Bonnie Farraday lives for music. She lets every note into her heart, and she doesn't understand how someone as talented as Cromwell can avoid doing the same. He's hiding from his past, and she knows it. She tries to stay away from him, but something keeps calling her back.
