Artemis Fowl - The Eternity Code by Eoin Colfer

I really liked this book because I have already read the first 2 books from the Artemis Fowl series. There are 7 books in all. Artemis Fowl is a 12-year-old, criminal mastermind. He devotes his mastermind to illegal plans on how to get money. His 7-foot servant Butler helps him by protecting him and doing things like creating "diversions" and kidnapping. In Artemis Fowl, there also are the elves, fairies, trolls, goblins and others. The elves, thanks to a centaur called Foaly, have technology that humans don't even dare to think of. 

I really liked this book because I like adventure stories with high-tech and masterminds involved.
