Xhex from the Black Dagger Brotherhood series. I don't know much about Xhex except these few facts: She's a symphath. She works for Rehvenge. She's tougher than hell. She seems to like John Matthew/Tehrror a lot too. We seem to see her more in Lover Enshrined, which can only mean that we're going to see more of her in the books to come. =] And for those of you who have read Lover Enshrined, you'll love the quote. XDDDDDDDDD
Artist Note: Sorry it took me so long to add this!
lol, while Xhex sounds like an intruging female judging from the description given by warden, putting keira as her is nothing against keira, she's cute, funny etc, but not tough, grab-me-by-the-balls amazon that Xhex is supposed to be ^_^
