Artemis Fowl has been one of the most entertaining series in children literature over the last ten years. This is a worthy edition to the cannon though not up to some of the earlier books.
This is a claustrophobic novel, taking place over less than a day in the life of Artemis. There are so many characters to fit in to the story that Mr Colfer uses the clever trick of making many of them fill two roles at the same time. The pacing is good, but I felt I was in a tunnel most of the time. There were only a few occasions when Artemis has his head up and is scheming. I would have loved the final book to have played to the genius part, but it was not to be.
On the good side Mulch plays a major role in the plot and when he is in action this story flies (quite literally in places). The scatological jokes are flung without regard for innocent bystanders and it was a joy to behold (from a safe distance.)
I shall miss Artemis Fowl. The journey has been a great one.
Go buy this book because you wont regret it. It's still head and shoulders above most of the pack.
