It's going to be fantastic!
I loved the adventures of Artemis Fowl, and it looks like his younger brothers will carry on in fine fashion. There will be bad guys to fight, technology that's a lot of fun to read about, and fairies and pixies and trolls aplenty. I didn't even know Eoin Colfer had started a new series until I saw this listed on Bookish First, but now I'm adding it to my must-read pile.
