Artemis Fowl: The Time Paradox

Artemis Fowl: The Time Paradox - Eoin Colfer I found this book to be a bit unbelievable. It felt more like the author was just trying to think of a new idea for these characters. I think that the series should have ended after the fifth book. However, they insisted and I feel as though it was basically: "Hmm, I want to write another book. New idea? Naaa too hard, I'll use Artemis Fowl. Let's see... ah yes, we'll go back in time! Umm, because of a... sickness, that we've never heard of, and, uh.. A LEMUR! Great 400 pages!"
Some of the content was good, but this series is getting tired. Maybe it's time to retire it.
