Beware the Boggart!

"My name is Jared Grace. Not too long ago I moved with my sister, Mallory, and my twin brother, Simon, to Spiderwick Mansion. The mansion was a strange old house; its kitchen was stocked with tons of weird things like tomato sauce and honey. And I soon found out why. My great-great-uncle, Arthur Spiderwick, had uncovered a whole world of fantastical creatures: brownies, sprites, goblins, and even an ogre! And he had to protect himself against them -- as I do now. In this book I will show you how to protect your own home against these invisible creatures because what happened to me could happen to anyone!"--P. [4] cover.
