Query: I liked some of it...

I think I liked this book until I got about halfway through. Then things started to go downhill. Without giving too much away for people who might want to read it, some of the story elements seemed corny, and parts of the ending are hackneyed and contrived. I had such high hopes for this book (and the next ones in the series), but it left a bad taste in my mouth. I don't think I'll be reading the next one... if I do, it'll have to be awfully good to hold my interest through another 300 pages!
