The Grace children turn to Great-Aunt Lucinda for help in this repackage of the third book in the #1 New York Times bestselling Spiderwick Chronicles.

As if being attacked by goblins and a bridge troll weren’t enough, Jared is now being targeted by Thimbletack. Simon is keeping an injured and very hungry griffin hidden in the carriage house. And Mallory is convinced the only way to get things back to normal is to get rid of the Guide. But that doesn’t seem to be an option. With more creatures from Arthur Spiderwick’s Field Guide to the Fantastical World Around You popping up, the Guide seems to be the only protection the Grace kids have. But why do the faeries want it so badly? There’s only one person to go to for answers—crazy, old Aunt Lucinda!

In honor of the tenth anniversary of the #1 New York Times bestselling Spiderwick Chronicles series, which has more than 12 million copies in print worldwide, this edition of Lucinda’s Secret features a larger trim size and an original jacketed cover with all-new art from Tony DiTerlizzi.
