Query: I couldn't pick this book up.

I had a very difficult time getting through this book. I had to force myself to sit down and finish it. Although Katya's thoughts and actions did make me laugh out loud a few times, I had a hard time caring about what happened to her. This may be why I found myself reading the same page over and over, and still my mind wandered.
