This book begins in Barcelona, Spain, where Artemis Fowl II and his bodyguard, Butler wait for and eventually encounter a demon. Here they see a blond
girl accompanied by two adults, one with a set of crutches. Artemis, having just hit puberty, is extremely attracted to her. Later, they see the demon who
appears though off time and place, and takes Artemis on a little joy ride through time. Butler has a hand on his shoulder, and would've been taken too, had

Jonah Lee). She manages to knock him out.
When Artemis distracts Minerva, Holly and №1 escape. Kong, w
