Deny All Charges (The Fowl Twins, Book 2) | Eoin Colfer

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. Their chase will take them across continents, deep underground, and into subaquatic super villain lairs. They will be shot at, covered in spit, and at the receiving end of some quite nasty dwarf sarcasm. But will Beckett be able to come up with a genius plan without a genius on hand...?
