Basically, He comes across a old fairy who has this book to unlock mysteries of a WHOLE underground base full of Trolls, fairies, elves, goblins and gnomes. But they not like in fairy-tales these fairies can fight. Holly, the main elf/fairy you read about, goes and tries to top up her magic by planting an acorn in the ground so 'mud men' (humans) cant see them but ends up getting trapped by Artemis and taken prisoner in his house ' Fowl estate '. Meanwhile the police force ( that Holly's a part of) see that she's been taken prisoner and launch a rescue team.
Aaaaaaaaaaaaaaaaaaaaaaand I'm gonna stop there so I don't spoil the rest of the story, heh heh. Who's hating me right now? *Chuckle*
I rate this this book 5/5! And as I'm NOT fond of books that says a lot!
I've now started reading Artemis Fowl: The Arctic Incident
