Colfer, Eoin. Artemis Fowl: Opal deception

Colfer, Eoin. Artemis Fowl: Opal deception [#4]. Hyperion, 2005 [0-7868-5289-5]

After having his mind wiped of fairyworld memories at the end of Book 3, Artemis opens this book in the act of stealing a famous painting. Meanwhile Opal Koboi, a former rival schemes to get out of jail and is out to get even with Aretmis, Butler, and Captain Holly Short. Of course the old gang (including Mulch) gets together to try and defeat Opal. It would be so much easier if Artemis and Butler could get their memories of the fairyworld back. This 342 page book is another great adventure. It you have the others, don't miss this one.. and if you don't have them.. get them.
