I'm not sure exactly what age group this is targeting but young adult feels a bit too old. The plot is quite simple yet engaging which is a positive, and the characters are quite nicely done. There's some character development with Edward however the others are much more one dimensional. It needs some more exposition to explain the world,  I know there're others in the series but some of the plot points in this come across as very convenient and a bit "it's like this because of magic rules which were never hinted at or explained".

It's a classic and I can see why children would enjoy it but personally I found the female characters to be formulaic and the writing style a little dull. Many paragraphs are overly descriptive with a lot of "and x" chaining them together.

The world however is a good one, and with more depth I imagine it will be a decent series, I'll continue to read them to my son as he grows up but I think there're better examples of the genre.
