This one has been the most difficult battle yet. If i had never read Highlord Skies i would have said Mina right away, but i really enjoy the Kit we get to see in that novel.
After much deliberation i'm going to have to just barely give it to Kitiara. Her scenes in Highlords Skies and at the end of Test of Twins are what push her over the edge for me. Her death at the end of legends is bone chilling. And the fact that i think Mina's character traits in War of Souls gets a little old towards the end. Even if it gets better in Dark Disciple.
