Bright Shadow — Avi

In one day, Morwenna has gone from being the lowliest servant in the king's castle to the most powerful person in the land, for she has become the wizard, the bearer of the last five wishes in the kingdom. But with her new gift come rules: She cannot wish for any more, she cannot wish for anything for herself, and if she speaks of them to anyone, both she and the wishes will be gone.

Morwenna's gift is a greater burden than she ever could imagine. Can she make the difficult, fateful choices which lie before her?
