Dark Notes introduces us to Catherine "Crimson" Dalton, a musical prodigy with a shattered past. At seventeen, she carries the weight of a horrific trauma that has left her selectively mute and emotionally fractured. She navigates her senior year at a prestigious private high school not as a typical student, but as a ghost surviving on the fringes. Display → The UI shows the PDF viewer
Enter Dominic Hawkins, the new piano teacher. Dominic is not just an educator; he is a maestro with a dark, controlling streak and a past of his own. When he discovers Crimson’s talent—and the horrific secrets she is hiding—he does not report her situation to authorities or child services. Instead, he makes a dangerous, life-altering choice: he takes her under his wing, initiating a relationship that blurs the lines between mentorship, guardianship, and romance.
