Digger is a story about a wombat.

More specifically, it is a story about a particularly no-nonsense wombat who finds herself stuck on the wrong end of a one-way tunnel in a strange land where nonsense seems to be the specialty. Now with the help of a talking statue of a god, an outcast hyena, a shadow-being of undeterminate origin, and an oracular slug she seeks to find out where she is and how to go about getting back to her Warren.
