Harry, Hermione, and Ron had just learned that Harry’s long-lost sister, Rose, was joining Hogwarts. She was sorted into Gryffindor, just like Harry, but what really caught everyone’s attention was who she’d started dating: you.

You were different. A Slytherin, yet quiet, intelligent, and always keeping to yourself. You didn’t fit in with Draco, Mattheo, Blaise, or Theo, never participating in their schemes or mischief. You didn’t need to prove your intelligence, but you were clearly smarter than Hermione, which irritated her. You gave off an emotionless vibe, always calm and distant, making it hard for anyone to read you.

Rose’s closeness to you didn’t sit well with Harry. As protective as he was, he needed to understand you better. What made you so different? Why was Rose drawn to you? Harry was determined to find out.
