Invasion of the Junkyard Hog

Following Attack of the* Shark-Headed Zombie* and *Stampede of the Supermarket Slugs* is Bill Doyle's third tale of monsters and magic. 

Mr. Cigam has a new job for Keats and Henry—a job working for his mixed-up stepsisters, Lillian and Beatrice. The sisters have lost a magical compass at the Tophat Junkyard, and ever since then, they've lost their sense of direction as well. Now they need* pleh! *(That's help spelled backward.) But for Keats and Henry, finding the compass isn't going to be easy. Something else is searching for it, too—a magic-sniffing junkyard hog with wings, long sharp tusks, and an appetite for destruction!
