Violet Wings (Violet Wings #1)

the long version

When Zaria Tourmaline and her fairy classmates receive their wands at age 12, she is shocked to discover that she and her friend Leona have extraordinarily high levels of magical ability and power reserves, talents that have become almost unheard of in Feyland. For Zaria the news is tinged with bitterness, for she cannot share it with her parents, who disappeared three years earlier on a mission to Earth. Despite (or perhaps because of) this, she is drawn to the human world, and creates a stir when she is spotted by a pair of children. Now Zaria must face the consequences of her carelessness while fending off the attacks of her sinister mentor, Lily Morganite, who seems determined to get her hands on Zaria's powers.
