Violin by Anne Rice is not a vampire story. Instead, it's a ghost story. The main character is haunted by a ghost and his ghost violin. The ghost is trying to drive her crazy. The violin just wants to be played.
So she steals the violin from the ghost and plays it. Amazing considering she doesn't know how to play the violin. In the end, she gives the violin back, the ghost goes into the light and she moves on. Playing a different violin.
This story moved faster than Rice's vampire novels. (But not as fast as the mummy) So it was definitely an enjoyable read. But as I approached the end, something about the book began to bother me. The main character began to focus so much on the violin, that the ghost became lost. A problem for me, because I found the ghost much more fascinating than the main character.
I kept wondering why he set out to drive her crazy. Rice danced around this issue, almost answering it. I never felt satisfied that it had truly been answered. I don't need an author to come out and draw the answer, but I felt like I was missing a dot or two here.
