Artemis Fowl and the Opal Deception

The book I read is called Artemis Fowl and the Opal Deception, it is written by Eion Colfer and the genre is sci-fi and adventure because Artemis and his fairy friends travel between countrys.

In this book a pixie named Opal Kobi was planning world domination with 2 other pixie twins Opal Kobi mesmerized (hypnotized) a famous scientist and became his daughter.
The scientist was planing to drill a big drill into the ground to get iron but Opal wanted him to drill into Haven City (the fairy world) and connect the 2 worlds together, can Artemis and his friends save the day...
