But they had no idea how amazing these changes would be.

Griffins, goblins, hobgoblins, elves and gnomes, trolls and forest spirits! This discovery led to a series of incredible encounters, dizzying adventures and dangerous scrapes. Although many fairies are quite sweet and peaceful creatures, there are also those with whom it is better to never meet. And one such monster has been hatching plans to take possession of Arthur Spiderwick’s book at any cost for eighty years...
