Firebird - Harbingers, #3

Keera has revenge in mind, and boundless confidence. After all, her magic powers are second to none. With outrage, she finds her powers stripped away from her. When she finds she must fight her battle with only her wits and her grit, how can she possibly prevail? She is young and has no war-skills. But the girl has friends: an old mage who helps her, a young man with a twinkle in his eye who can't get her out of his mind-and a ghost. Book III of the Harbingers fantasy series.
Can be read as a stand-alone novel.
