The Frey Saga (3 Book Series)

From Book 1: Unaware she's been bound from using magic, Frey leads a small, miserable life in the village where she's sent after the death of her mother. But a tiny spark starts a fury of changes and she finds herself running from everything she's ever known.
Hunted by council for practicing dark magic, she is certain she's been wrongfully accused. She flees, and is forced to rely on strangers for protection. But the farther she strays from home, the more her magic and forgotten memories return and she begins to suspect all is not as it seems.
