"Hit or Miss"
I think this is the type of book you either love or dismiss, depending on your personality and age. I know the intended audience (ages 8 - 16) will love this. For me as an adult, I absolutely loved it as well. But that's because I enjoy a good story with interesting characters. This is not a serious book, though there are a couple of serious moments. The mystery in Paraworld Zero was just enough to keep me guessing. I wish there was a little more romance, but the characters are fairly young (12 through 14), so I understand why the romantic aspects were watered down. There better be more romance in the sequel! I was hoping to see Simon at the magical school, but as it turns out, that'll be in the next book. I'm looking forward to it.
As for the narration, I actually enjoyed the funny and peculiar voices. They were well done and kept me entertained. The prolog is awfully serious, but it lightens up considerably after that. Highly recommended.
