Warm Moonlight by Joseph Wurtenbaugh
This was a Kindle Single so I'm not sure if this is available if you don't have a Kindle.
This is a short story of a woman telling her great-grand-daughter an amazing tale of adventure, peril and rescue. The story is told as a short chapter in the life of the grandmother. It is up to the young woman whether to believe if it is true or not and how to use the information.
This is a really nice short story. I recommend it as a quick read for an afternoon.
