Fan fiction for The Purge, one where a group of people holding out to avoid the Purge face betrayal..from within the family. More gruesome material than my usual, just fair warning.
A mother and her son plan for a fun weekend together at a cottage park, but their weekend gets washed out by a terrible electric storm and they are forced to stay indoors. However, they do discover a way for them to make the weekend turn out wonderful despite the storm and being trapped inside.
