I am currently on book one of the series and I think it is amazing so far, I can't help falling in love with it.
I've read them all. They won't dissapoint you. Also, maybe you already know, but Warner Bros. is making the series into movies after they finish filming the Harry Potter ones. Oh, never mind. Just finished reading your description. Anyway, each books introduces more and more characters and twist plots. As you say, it's hard not to fall in love with the setting and characters.
The story doesn't sound that bad actually, but the bastardisation of English words... Eugh =S I suppose it is written for kids, but still.
