Catch the Moon, Mary
By Wendy Waters. Fans of Anne Rice and "The Phantom of the Opera" will enjoy this paranormal romance/horror novel that asks creative questions about God, love, and power. The angel Gabriel has tried so long to enlighten humanity that he has become bitter and violent. He has lost faith in love, and believes that humanity must be redeemed by force. He rescues an abused girl who is a musical prodigy, in exchange for a claim on her talent—but her love and innocent wisdom make him question whether the end justifies the means.
