How will Artemis's life change now that the story is over?

Artemis received his wish from Holly. She used her magical powers to heal Angeline Fowl. In the end of the book, Angeline comes out of her room insisting that the Manor be decorated for Christmas. She recognizes her son. She apologizes for her behavior of the last few months and notes that things will be different now that she will no longer be living in the past. For Artemis, this means he will return to being a boy and a son; one without being able to call all of the shots. Artemis considers this a gift.
