Loved it loved it loved it! It was wonderful! Solid, quick-paced plot full of surprises, multi-dimensional characters and an ending I never would have guessed. I love to be surprised by the plot of a book. I loathe reading an ending in which a brand new character is suddenly introduced to resolve the crisis.
One thing I was probably wrong about was classifying the book as YA. It is actually probably considered a children's book. I don't pay much attention to these categories since I suspect they are used mostly for marketing purposes and tend to have little to do with how much I will enjoy the book. In this case I suspect Colfer wrote it for the 8-12 year old set. He is very careful not to use curse words and that is definitely not indicative of YA lit. There is also a sweet, magical revelation near the end that must be meant for children, but I loved it too. "You're only young once, but you can be immature forever," that's what I say.
There are at least seven books in this series and I will definitely read more. Thanks, Eoin, for a lovely time.
