So far, I'm not loving this. I've also read Eoin Colfer's Artemis Fowl and I didn't love that either. The writing feels very, very detailed to me and simple events seem to take forever to get through. I like the general idea of the story but the execution doesn't particularly appeal to me. That being said, I understand why young readers enjoy the stories and would certainly recommend the books to students.
Finally finished! This is one of those works that makes me wonder if I would have liked it better in print than audio.
