Hex Hall novels

Three years ago, Sophie Mercer discovered that she was a witch. It's gotten her into a few scrapes. Her non-gifted mother has been as supportive as possible, consulting Sophie's estranged father???an elusive European warlock???only when necessary. But when Sophie attracts too much human attention for a prom-night spell gone horribly wrong, it's her dad who decides her punishment: exile to Hex Hall, an isolated reform school for wayward Prodigium,...

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.
