Tale 10 from The Secrets of Castle Drakon by Tee Geering
Fantasy – Sisters come to scary Castle Drakon with their parents. Maya is over-weight and is constantly picked upon. She takes on a wager to sleep alone inside the crypt and while her body sleeps she is taken up to Olympus, where the gods of ancient times live. She discovers a different self and is soon in demand as a lover by the gods, including Zeus himself. Mayhem ensues!
This is a tale fitting to the legends of old times. Boy, do not trust the gods (or goddesses!) for they do not take kindly to mortals, do they? A great yarn.
