Mystery, madness and mayhem are afoot in the penultimate book in the
bestselling Spiderwick Chronicles.

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 Spiderwicks Guide? And now that the Guide has mysteriously disappeared,
will the Grace kids finally be left alone? Dont count on it!

At school, someone is running around pretending to be Jared, and its not his
twin, Simon. To make matters worse, now Mallory has disappeared and something
foul in the water is killing off all the plants and animals for miles around.
Clues point to the old abandoned quarry, just outside of town, where there is
news that a creature with plans to rule the world has offered them a gift to
join with him
