Deny All Charges by Eoin Colfer

Artemis’s little brothers Myles and Beckett borrow the Fowl jet without permission, and it ends up as a fireball over Florida. The twins plus their fairy minder, the pixie-elf hybrid Lazuli Heitz, are lucky to escape with their lives.

The Fowl parents and fairy police force decide that enough is enough and the twins are placed under house arrest. But Myles has questions, like: who was tracking the Fowl jet? Why would someone want to blow them out of the sky? These questions must infuriate someone, because Myles is abducted and spirited away from his twin.

Now Beckett and Lazuli must collaborate to find Myles and rescue him – not easy when it was Myles who was the brains of the operation.
