To him, she is his angel, his only weakness, and the one person he will never allow anyone to take away. But when Brielle steps into an elite university under a false identity, her beauty draws dangerous attention, her kindness pulls her into the shadows of the underworld, and secrets begin to close in around her. The world believes she is just a poor transfer student. No one knows that behind her stands a man powerful enough to destroy anyone who dares touch her.
