Good as far as it goes
I'll just come right out and say it, Kitty - your other work is better! Don't get me wrong, this is a good story; the characters are fun and the plot moves along nicely, it's just... well, it reads like a first novel. (Which makes sense, since I know that's what it is.) It works well as a kids' book, as the other reviewer said, but for a 27 year old (like me) it's quite obvious where things are heading. As far as this goes, it's very good, but I get the feeling you took what you learnt writing this and applied it to your other novel, and that is a much better and more involved story. I will definitely read this to my 14 year old niece though - she'll love it!
Read the story now
To sum up; a good book for anyone under 16, but will leave adults wanting more.
