I have finished The Mage's Daughter, Book 2 of Lynn Kurland's Novels of the Nine Kingdoms.
Nothing is as it seems in the Nine Kingdoms, and no one, apparently. But the heart endures even in the face of rampaging trolls, grumpy royal grandfathers, and seriously evil magic. They say that ignorance can be overcome but that prejudice will destroy you, and thank goodness Mhorghain overcame it. But overcoming what killed her mother will be a different matter altogether, even with archmage Miach by her side.
