Double Minds by Terri Blackstock

Parker writes Christian songs and has had success.  Now she is being asked to tone down the Christianity in her new songs and take out some of the Christian lyrics in her existing songs.  Will she succumb to the promise of financial gain?
Blackstock gives us an inside view of the Christian music industry.  There are those who want to "cross over" and have hit songs in the secular market.  One manager of a Christian singer is willing to steal lyrics to ensure his artist remains successful. 
True to Blackstock form, there is a murder in the plot as well.
I liked the book but I listened to it on CD and that was not as good as it could have been.  One character's voice was described as a "radio voice" but when it was portrayed it was squeaky high.  I'd suggest you read the book but skip the audio edition.
