You can hear the Lauren Grof read "The Midnight Zone" here. https://www.wnyc.org/story/lauren-groff-reads-midnight-zone/ although I read it in her collection of stories called FLORIDA. It is also available to read in a May 2016 issue of the New Yorker.
One of Groff's greatest strengths (for me) is her ability to make a landscape come alive. And in this story, it's a woodsy, primitive area of Florida filled with sink holes, wild animals, dangerous men, snakes, etc.
A panther has been spotted just before the father of a young family is called away. Immediately, we are on the edge of our seats as readers. He will be gone two days, leaving his wife with two small boys, no Internet, and even getting the cell phone to work is iffy. The mother has already admitted to not being the most engaged mother in the world. And it seems like she may now be ill with an unnamed malady.
Very quickly things spin out of control, and in trying to change the sole light bulb, with her son holding the stool, she falls and suffers a nasty head injury. She wakes to find her two boys looking down at her and they try as best they can to care for their injured mother. She comes in and out of consciousness and fantasizes roaming the woods around them, seeing the dangers awaiting them. The boys tend her and when their father returns, she can see from his face just how dire her situation was.
I very much admired that Groff never allows the reader to be off the hook in terms of awaiting a panther's arrival or some similar dire fate. She creates a threatening environment although the boys seem unaffected by it. It is the mother who is terrorized. A great story for me.
