Unfamiliar faces, new friends, and even new bullies await 11-year old Eric Del Bosque as he moves into his new neighborhood of Ashen Forest Estates, a slice of small town America. The new home and new rules are the least of his problems as Eric learns that his bedroom faces the den of a nightmarish rural legend that also happens to exist outside normal space and time. Soon, beloved pets begin to vanish all over the neighborhood and only Eric and his new friend Heather Foster can piece together the mystery of the legendary beast and the real danger of growing up in Grizzlydale. If they can avoid being grounded for the summer, that is.
