An original and hilarious story of wayward goblins, inept heros and children who save the day, and the books.

When Anna and Nils meet Bob Gribble after school one night, little do they know that his true identity is Gribblebob, a goblin from the other side of the veil.

As the mystery of his presence in their village unfolds, Anna and Nils's after-school routine is quite tipped on its head: they become embroiled in a wonderful adventure to save some books from a very evil witch, while also dealing with an invisible dog and two not entirely heroic heroes and making lots of new friends along the way.

A delightful, hilarious and brilliantly inventive adventure story by debut author David Ashby.
