Y/n Black never asked to return to Hogwarts. After years at Durmstrang mastering dark magic, she’s sent back to finish her sixth year among Slytherin’s finest — confident, dangerous, and impossible to ignore. Her biggest problem? Mattheo Riddle — arrogant, magnetic, and her sworn rival since childhood. When they’re forced to work together under Snape’s watch, their rivalry ignites into something far darker — and far harder to control. Enemies to Lovers. Dark Magic. Forbidden Attraction.
