Alex the Dog and the Unopenable Door

ISBN: 9780571294619

Alex Jennings is a boy with a problem.

But with the help of a talking dog and a girl with unfeasibly sharp teeth, he just might have what it takes to cross the Forbidden Lands, escape the evil Davidus Kyte, and find out what lies beyond the Cusp ...
