Artemis Fowl: The Eternity Code
Eoin Colfer
 Artemis Fowl II, the 13-year-old criminal mastermind, has created a supercomputer which he calls the "C Cube", from stolen fairy technology. It far surpasses any human technology made so far. When Fowl meets Chicago businessman Jon Spiro to show him the Cube, Spiro ambushes Artemis and steals it. In the process, Butler, his bodyguard is killed by one of Spiro's staff. However, Artemis manages to revive him with the aid of cryogenics and fairy healing magic, courtesy of Captain Holly Short of the LEPrecon squad. After Butler is revived, Artemis convinces the LEP to track down the Cube. They agree on one condition: that Artemis' mind is to be wiped later. They head to The Spiro Needle, where Jon Spiro has held the Cube. The Cube is recovered with the aid of Butler's sister and Mulch Diggums, who is later incarcerated. Nearing the end of the book, Mulch discovers that Artemis has cleared him of all charges and tasked him with restoring Artemis' memory, which is wiped at the end. In the epilogue, it is revealed that the LEP questioned him to reveal any plans he had to retain his memory, but he managed to fool them, and his plans remained secret from the LEP.
