A Wicked Raven

Assassin.
Raven.
Corbin is one of those elusive raven shifters and the best assassin in his flock. The Council of Paranormals assigned him to watch a nineteen year old witch with orders to kill if need be, but the last thing he expected was to fall for his mark. Now that he knows who she is, what she is...will he follow orders or stray from the path?
