Query: I enjoyed the story until...

A book's ending can make or break it. While the majority of this story was fairly decent, it fell apart at the ending. I liked the idea that the young girl was telling her story from heaven. Unfortunately, the author seemed to have been struck with a case of writer's block at the end and asked a stranger to write the ending. That could be the only explanation. Why else would the girl come down from heaven to have sex with some boy, but never come down and reveal her killer?
