This week's question:
"Who's your all-time favorite book villain?"
Answer: Devlen Daviian from Maria V. Snyder's Glass Series
Although if I were to dress up as a Harry Potter character, I would be Bellatrix Lestrange - mostly because I keep my hair big and crazy too.
(I just loved this question so much I had to jump on the book blogger bandwagon - hope they don't kick me off!)
My all-time fav not-yet-published villain is a gal I'm writing in my third novel. She has become so important to the plot I've considered making the sequel about her. I adore her so much that I take glee in letting her win over my protag time and again. :)
