This story is a sequel to Courage the Cowardly Dog In: Mare-anormal Activity
Courage has been returned home, and everything seems to have to returned to normal. Unfortunately, dark forces have awakened, and have no intentions of staying quiet...
I would suggest reading Mare-anormal Activity first, if you haven't already.
