Let the story of my niece and nephews be a warning. The more you know, the more danger you're in. And trust me, you don't want to meddle with the Little People. — S.S.

Things at the Spiderwick estate are getting completely out of hand. If being attacked by a band of marauding goblins and almost eaten by a bridge troll wasn't enough, now Jared is being harassed by Thimbletack, the house boggart, and Simon has a very hungry griffin recuperating in the carriage house. Mallory is convinced that the only way to stop the madness is to chuck the Guide. But that's not an option. Only one person can help solve this mystery - thier crazy old Aunt Lucinda.
