The Fowl Twins

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. When Myles is abducted and spirited away from his twin, Beckett and Lazuli must collaborate to find Myles and rescue him.

Myles and Beckett Fowl are twins but the two boys are wildly different. Beckett is blonde, messy and sulks whenever he has to wear clothes. Myles is impeccably neat, has an IQ of 170, and 3D prints a fresh suit every day – just like his older brother, Artemis Fowl.

A week after their eleventh birthday the twins are left in the care of house security system, NANNI, for a single night. In that time, they befriend a troll on the run from a nefarious nobleman and an interrogating nun both of whom need the magical creature for their own gain.
