I know, there have already been Artemis Fowl threads. But earlier today I was in my local bookstore to pick up a copy of The Subtle Knife, the second book of the His Dark Materials trilogy. All of a sudden I realized, wait a minute; there are four Artemis Fowl books there, that cant be right. But it's true, there is a new Artemis Fowl book called The Opal Deception. I haven't picked it up yet because I don't know what its like. Has anybody read it? Does anybody have any thoughts on it? Is it worth buying?
