The Fowl Twins
In this first book of a brand-new series, we meet the younger siblings of Artemis Fowl. Myles and Beckett are twins but the two boys are wildly different. 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.
