The Eternity Code Summary & Overview

Artemis Fowl is ready to leave crime behind—or so his newly reformed father expects. Before embracing respectability, the thirteen-year-old genius plans one final deal. His bargaining chip is the C Cube, an astonishing computer assembled from stolen fairy technology and capable of breaching virtually any security system on Earth.

Artemis presents the device to ruthless communications billionaire Jon Spiro and demands a fortune to keep it off the market. Spiro responds with an ambush. The Cube is stolen, Butler is struck down protecting Artemis, and the supposedly flawless scheme becomes a catastrophe with consequences far beyond money.

Now the Cube’s signals threaten to expose the hidden fairy civilization beneath the human world. With time running out, Artemis must recover his invention from a heavily guarded Chicago skyscraper while facing enemies who know exactly how dangerous he is. To succeed, he will need fairy magic, criminal allies, the Butler family, and a plan audacious enough to outwit a man who believes everything can be bought.
