There is a great possiblity that this copy will be autographed by the author herself seeing that I'm going to go and see her speak next week.
For an even better chance to win, post about this contest on your own blog (linking back to this post) and your name will be entered twice! The winner will be announced on March 13, 2008.
ETA: I was able to get 2 autographed copies of Change of Heart to giveaway. So there will be 2 winners in this contest!!
