Artemis Fowler and the lost colony. Eoin Colfer. 2007.

I have waited a long time for young criminal mastermind Artemis Fowler to meet his match. Finally, it’s happened.

A second juvenile genius has discovered that fairies do exist and she is determined to capture one for scientific study. And not just any fairy. The newcomer intends to trap a demon - the most human-hating species unknown to man.

Only an ancient time spell separates the demons from mankind - and Artemis must prevent it from unravelling. If he fails, the bloodthirsty tribe will re-launch their quest to wipe every human from the planet. Because that’s what demons live to do.

There can only be one winner - and this time it might not be Artemis Fowler.
