The Atlantis Complex. We’ve all been hearing about it, and finally, the tiniest bit of information has been revealed!
Only the slightest bit of the plot has been revealed; but in an interview Colfer revealed that Artemis Fowl II somehow joins Opal Koboi in her prison in Atlantis and begrudgingly returns to his criminal ways, though this has not been confirmed to happen. A fan also stated that Colfer told her that the magic in Artemis causes him to develop OCD and multiple personalities, known by fairies as the “Atlantis Complex”. Artemis then becomes an entirely nice and kind person without his criminal ways, who could think up save his friends no matter what the situation.
In that interview, they give us a reason to think that Artemis may still have a little bit of magic left… ‘the magic in Artemis causes him to develop OCD’. We may be jumping at shadows, but there’s a chance there’s still a bit of magic in him!
As of December 25th, 2009, Amazon has released a publishing date of July 13th, 2010, although the publishing date is still subject to change.
Eoin Colfer had stated that The Time Paradox may not be the last book, but will be the last for at least 2 years as of the publication of book VII. This has been confirmed by the announcement of Artemis Fowl: The Atlantis Complex. At a questioning session, after Fairies, Fiends and Flatulence session in Worchester, he revealed that the next book would explain about a link between Holly and Artemis’ birth. He has also let slip that he has plans to have Artemis end up in fairy prison with Opal Koboi (of the present).
