Harriet Potter has never fit in—not with the Dursleys, not with the snakes in the garden, and certainly not with the way her shadow slithers when she’s afraid. When a letter arrives from Hogwarts, she hopes for answers. Instead, she finds more questions: Why does Professor Snape watch her like she’s a ghost? Why can she whisper to shadows as easily as she breathes? And why does Professor Tom Slytherin smile at her like he already knows how her story ends? Magic here is alive, hungry, and tied to bloodlines older than time. Harriet’s oddities aren’t flaws—they’re fragments of a forgotten inheritance. And someone is waiting for her to remember.
