I read the book ARTEMIS FOWL: THE ETERNITY CODE by Eoin Colfer. The main character, Artemis Fowl, uses confiscated fairy technology in a scheme to restore his family's wealth. However, when the technology is stolen, Artemis and friends go on an adventure to get it back.
The mood of the book is one of my favorites, as it often changes. In the begining the mood is cheery. Then it changes to helplessness. After that it changes to determination.
The ending of the book is sad. Artemis is being mind-wiped of his fairy memories; however, there is hope that he can regain his memories. After all, he is a genius. -Bruce H
