Hex Hall novels

When Sophie attracts too much human attention for a prom-night spell gone horribly wrong, she is exiled to Hex Hall, an isolated reform school for wayward Prodigium, a.k.a. witches, faeries, and shapeshifters.

Just as Sophie Mercer has come to accept her magical powers as a demon, the Prodigium Council strips them away and leaves her alone, defenseless, and at the mercy of her enemies the Brannicks, a family of warrior women who hunt down the Prodigium.
