From publisher blurb:
On the eastern face of a low mountain is a forgotten door. Few of the locals know about this place, and those few who do know this place shun it for being haunted by evil creatures.
Occasionally some weary traveler will find his way to the door, seeking shelter from a storm or wolves or some other danger. Those people always disappear.
