First a pack vile, smelly goblins snatch Simon. Then a band of elves try to entrap Jared. Why is the entire faerie world so eager to get their hands on Arthur Spiderwick's Guide? And will the Grace kids be left alone, now that the Guide has mysteriously disappeared? Don't count on it.

At school, someone is running around pretending to be Jared. To make matters even worse, now Mallory has disappeared and something in the water is killing off the plants and animals. Clues point to the abandoned quarry just outside of town where the dwarves have taken over. Meanwhile, the faerie world's abuzz with the news that a creature with plans to rule the world has offered the dwarves a gift to join with him: a queen.

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 The Ironwood Tree features a larger trim size and an original cover with all-new art from Tony DiTerlizzi.
