From the publishers blurb:
An exiled king’s castle has aged centuries overnight, terrifying locals and passing travelers. Although relieved to be rid of the ruthless despot, farmers are fearful of what the small keep's sudden and unexplainable ruination could mean. Will some curse or foul magic now creep into their lands?
Rumors of the king’s remarkable wealth have lured adventurers and brave villagers into the perilous tunnels below the castle, but none have returned. Can anyone find out what is going on at Castle Grushnal?
