The Beginning

The book opens with Artemis Fowl in Barcelona, Spain waiting to find out if a demon will appear there because he apparently has been wrong several times before this so he waits patiently and shows off his mental prowess once again to Butler. They are just about to leave when it appears late and a few feet off target, as it lands Artemis grabs it and it pulls him into another time but Butler pulls him back since Butler is safely weighed to our dimension because he is wearing silver. They head back to the house. Holly, a fairy, is nearly killed doing Private Investigator work and Folly, a centaur who is a technology whiz, gets her to join Section Eight, a secret demon watching task force of the fairy police, provisionally after that. Artemis then goes to an opera house wear he watches another demon appear but this time Holly is there with him and follows the people who capture the demon. That's all I've read so far so I'll add more when I read more.
