Trail of Lightning

I haven't torn through a book in quite a while. The pace kept moving, no trips down side plots that don't move the story forward, etc. However, I did see several commonly used themes that brought down the enjoyment rating; a person that hates herself ALOT, and the big one, she really hates that good looking guy. And how about the ending? I'm trying to pretend it didn't end that way cuz I hate unanswered questions.
